Schübeler Technologies Supports Visionary Project of ETH Zurich

Friday, November 26th, 2021

Students realize bionic inspired morphing concept for the aircraft of tomorrow.
Rome, NY- A control concept inspired by nature and combined with morphing technology has now been realized by engineering students of ETH Zurich together with aviation experts. The eight-member student team is testing novel control concepts and construction methods in aviation. The aim is to reduce energy consumption and noise generation through reduced drag and to improve the maneuverability of the aircraft.

Schübeler Technologies actively supported this innovative project and provided both engines and technical expertise in an advisory capacity. “By participating in this project, we would like to contribute to the further development of aviation,” explains Daniel Schübeler, Managing Director of Schübeler Technologies. “The visionary approach of Bionic Flying Wing as well as the enthusiasm and creativity of the team excited us.”

The project aims to prove the feasibility of bionic inspired morphing concepts in the air. To this end, a deformable morphing wing structure with a three-meter wingspan was developed to be used in place of discrete flaps. A top speed of up to 100 km/h can be achieved with it. The wing structures are specifically deformed to replace conventional control surfaces. In this way, new design potential for the aircraft of tomorrow is opened up The main challenge of this approach is that the wing must be stiff – i.e., it must not flap – but still be able to be deflected. To achieve both, a healthy compromise had to be found. Because of its high strength and low weight, the team therefore opted for CFRP (carbon-fiber-reinforced polymer) as the construction material.

The requirements for the drive system used were also high. In the search for an efficient impeller that delivers the greatest possible thrust in combination with low power consumption, the team quickly came across EDF market leader Schübeler. On Schübeler’s recommendation, the team decided on the DS-51-AXI HDS model with an 1125kv motor and 12 lipo cells. This drive offers a thrust of 5.5 kg (about 55N) with a current consumption of 85 amps, which was perfectly suited for an aircraft of this speed, size and weight. Two fans are used and provide a total thrust of approximately 11kg (110N)

The HDS fan is a quality product designed for durability. The lightweight and highly shortened rotor assembly provides efficient operation through high smoothness. The blades are made of high-temperature, fiber-reinforced polymer, operate highly efficiently, broadband, and quietly. Strength is provided by the carbon shroud.

In a successful first test flight in June of this year, the team proved that bionic inspired morphing concepts can be used to safely control a flying wing aircraft. This was the product of countless hours of engineering and manufacturing, paired with the support of strong sponsors such as Schübeler Technologies.

DARPA’s Gremlins Program Demonstrates Airborne Recovery

Friday, November 12th, 2021

Successful Fourth Deployment Results in Airborne Recovery of Gremlins Air Vehicle to C-130

An unmanned air vehicle demonstrated successful airborne recovery during the DARPA Gremlins program’s latest flight test deployment last month. During the deployment, two X-61 Gremlin Air Vehicles (GAV) successfully validated all autonomous formation flying positions and safety features before one GAV ultimately demonstrated airborne recovery to a C-130.

“This recovery was the culmination of years of hard work and demonstrates the feasibility of safe, reliable airborne recovery,” said Lt. Col. Paul Calhoun, program manager for Gremlins in DARPA’s Tactical Technology Office. “Such a capability will likely prove to be critical for future distributed air operations.”

During the final experiment, the team refurbished an X-61 vehicle and conducted a second flight within 24 working-hours. In addition, many hours of data were collected over four flights including air vehicle performance, aerodynamic interactions between the recovery bullet and GAV, and contact dynamics for airborne retrieval. Unfortunately, one GAV was destroyed during the flight tests.

“Airborne recovery is complex,” said Calhoun. “We will take some time to enjoy the success of this deployment, then get back to work further analyzing the data and determining next steps for the Gremlins technology.”

Safe, effective, and reliable air recoveries promise to dramatically expand the range and potential uses of unmanned air vehicles in conflict situations. The GAVs can be equipped with a variety of sensors and other mission-specific payloads. They can also be launched from various types of military aircraft, keeping manned platforms safely beyond the range of adversary defenses. After air retrieval, the GAVs can be refurbished by ground crews to prepare them for another mission within 24 hours.

Dynetics, a wholly owned subsidiary of Leidos, is developing the Gremlin vehicles.

Schübeler Technologies And Vita Inclinata Partner To Improve Crane Load And Helicopter Rescue Litter Basket Maneuverability With Enhanced Thruster Systems

Friday, October 29th, 2021

Fan Systems Customized To Adapt To Harsh Operating Conditions
Rome, NY—October 28, 2021—Schübeler Technologies, a high-performance Electric Ducted Fan (EDF) innovator and manufacturer, and Vita Inclinata (Vita), developer and producer of helicopter and crane load stabilization and precision hardware, today announced a partnership to adapt Schübeler’s highly efficient and robust electric ducted fan (EDF) propulsion system to the Vita Rescue System Litter Attachment and lifting system. The exclusive production agreement allows for the rapid scaling of Schübeler Technology’s solutions to meet Vita’s demand for rugged and reliable thrusters.

Witness the system’s real-world capabilities in the Black Hawk helicopter rescue ops training race, legacy hoist vs. the Vita Rescue System video.

“The need for precision control technology to stabilize crane loads and helicopter rescue litter baskets cannot be underestimated,” said Caleb Carr, president, and CEO, Vita. “To help us further limit the swing and oscillation associated with lifting and transporting loads, we needed a bigger EDF. Schübeler Technologies has agreed to customize their EDF’s so that now we have robust fan solutions that fulfill the stabilization needs for both aerospace and industrial load stabilization applications—notably improving safety and maneuverability.”

Rather than simply delivering a product to spec, the partnership is essentially an extension of  Schübeler Technologys’ R&D work. As needs arise, systems can be built for Vita to address countless real-world challenges. For instance, a helicopter operating in a desert environment needs an EDF propulsion system that manages huge quantities of dirt and dust, while a rescue mission conducted at sea must have EDFs attached that will need to function after being submerged in saltwater. These products must remain reliable after repeated use in harsh environments, under the most intense operational scenarios. Achieving this high level of sustainability involves significant real-world testing—something Schübeler addresses within its R&D function. The Schübeler Technology and Vita partnership will produce custom-built systems tough enough to perform in any challenging conditions.

“Vita has a very smart and unique approach to load stabilization,” said Daniel Schübeler, founder and chief technology officer of Schübeler Technologies. “We provide the aerospace know-how—at the same time we work on these very special propulsion systems which deliver very efficient and robust thrust, fulfilling a very wide variety of requirements to meet the needs of Vita Inclinata.”

Vita was founded in 2009 by Caleb Carr, a former high school search and rescue volunteer who watched a friend die in the mountains partly due to difficult weather conditions rendering a rescue helicopter’s basket hoist unusable. What resulted was an ongoing quest to find specific solutions to problems of stability and load management in high-pressure environments. Vita has built a team of engineers and field experts that gives them inroads into various sectors—including the military and search and rescue operations. Schübeler Technologies, with its own 25-year history of developing some of the world’s best aerospace and industrial propulsion systems, is a natural fit to help Vita fulfill their mission.

“Our reputation in the field of electric ducted fans brings clients to us,” said Schübeler. “And then we don’t disappoint the people. We deliver.”

Air Force Refines Pilot Candidate Selection Process in Support of Rated Diversity

Wednesday, September 22nd, 2021

JOINT BASE SAN ANTONIO-RANDOLPH, Texas — Several Air Education and Training Command initiatives to remove barriers for qualified candidates in the pilot candidate selection process were highlighted in the Air Force’s six-month assessment of its initial Racial Disparity Report Sept. 9.

Pilot Candidates may now:

– Use their highest composite scores from any Air Force Officer Qualifying Test (AFOQT) rather than the most current score. 

– Complete the Test of Basic Aviation Skills (TBAS) up to three times, with the third requiring a waiver from the applicant’s wing commander or equivalent. 

– Re-take the AFOQT and TBAS after 90 days compared to the previous 150-day requirement for the AFOQT and 180 days for the TBAS.

– Participate in study sessions with other individuals who have not yet taken the test if the examinee has also never taken the AFOQT.

These changes came after extensive research conducted by the pilot selection process working group responsible for identifying potential barriers while upholding the standards of excellence in the Pilot Candidate Selection Method (PCSM) used since 1993.

“Our studies concluded that these changes will result in more qualified candidates of underrepresented groups being selected for training,” said Lt. Col. Brandi King, the working group’s Air Education and Training Command lead.

Prior flying experience a barrier to qualification

Prior flying experience, the second largest component of an applicant’s PCSM score, particularly poses a socioeconomic barrier to candidates without access to or financial means to pay for flying lessons.  To address this barrier, the Air Force now considers only a candidate’s initial 60 flight hours when scoring a candidate. 

“There is no evidence that more than 61 hours of flight experience poses a significant benefit to pilot training success,” said Dr. Katie Gunther, chief of strategic research and assessment at the Air Force Personnel Center. “The probability of success in flight training increases substantially from 0 hours to 60 hours, then relatively plateaus.”

The working group also found that removing the higher ranges of flight hours as part of the PCSM score would result in a more-diverse applicant pool.  According to the Validation of the Pilot Candidate Selection Method 2020 report prepared by the AFPC Strategic Research and Assessment branch, removing the four highest ranges of flight hour codes would have resulted in 69 more Hispanic, 47 more female, and 26 more Black/African-American qualified applicants over a 12-year period.

“Flying lessons are expensive and could potentially exclude qualified candidates from becoming pilots in the Air Force due to limited income or lack of opportunities,” said Brig. Gen. Brenda Cartier, AETC’s Director of Operations and Communications and the pilot selection process working group’s overall lead. “In order to ensure we do not eliminate otherwise qualified candidates, flight programs have been implemented at both The United States Air Force Academy and the Air Force Reserve Officer Training Corps. Cadets receive free ground and flight training, and an opportunity to gain critical skills and directly improve their competiveness for pilot selection boards.”

Pilot selection process

A PCSM score quantifies a pilot candidate’s predicted aptitude for success at undergraduate pilot training. This score is comprised of the AFOQT and TBAS scores, previous flying experience, and other “whole-person concept” merits such as grade point average, physical fitness assessment scores and class ranking.

“Data supports that the PCSM is the best single predictor of pilot training completion. However, it is imperative that we continue re-evaluating our selection methods and remove barriers that hinder rated diversity without compromising test integrity or lowering standards,” King said.

Teaching the Commando New Tricks

Friday, September 17th, 2021

HURLBURT FIELD, Fla. —

The C-130J is an incredibly versatile aircraft, and since it’s creation, it’s landed on rough fields, in arctic locations and even an aircraft carrier Yet, it cannot land on water, which covers about 71% of the planet. As national strategic objectives shift focus to littoral regions, Air Force Special Operations Command is advancing new approaches to expand the multi-mission platform’s runway independence and expeditionary capacity.

In partnership with the Air Force Research Lab’s Strategic Development Planning and Experimentation (AFRL-SDPE) directorate, AFSOC is developing an MC-130J Commando II Amphibious Capability (MAC) to improve the platform’s support of seaborne special operations. “The development of the MAC capability is the culmination of multiple lines of effort,” said Lt Col Josh Trantham, AFSOC Science, Systems, Technology, & Innovation (SST&I) Deputy Division Chief. “This capability allows the Air Force to increase placement and access for infiltration, exfiltration, and personnel recovery, as well as providing enhanced logistical capabilities for future competition and conflict.”

The development of a removable amphibious float modification for an MC-130J would enable “runway independent” operations, which, according to Trantham, would extend the global reach and survivability of the aircraft and Air Commandos. “Seaborne operations offer nearly unlimited water landing zones providing significant flexibility for the Joint Force,” Trantham said.

Utilizing the MAC capability may provide unlimited operational access to waterways to distribute forces if land assets are compromised. 

“MAC is vital to future success because it will allow for the dispersal of assets within a Joint Operations Area,” said Maj Kristen Cepak, AFSOC Technology Transition Branch Chief. “This diaspora complicates targeting of the aircraft by our adversaries and limits aircraft vulnerability at fixed locations.”

A task force of industry partners are closely collaborating with AFSOC and AFRL-SDPE to bring the vision to life. A five-phase rapid prototyping schedule will lead to an operational capability demonstration in only 17 months while de-risking the concept for a future potential MAC program of record that could field MAC for MC-130Js but also potentially field a similar amphibious capability for other C-130 variants with only minor variations.

AFSOC and private sector counterparts are currently testing MAC prototypes through digital design, virtual reality modeling (VR), and computer-aided designs (CAD) in a virtual setting known as the Digital Proving Ground (DPG), paving the way for digital simulation, testing, and the use of advanced manufacturing for rapid prototyping and physical prototype testing.

According to Trantham and Cepak, the DPG can deliver mission review, aircraft system analysis, design ideation, engineering risk-reduction, virtual reality, concept imagery, feasibility studies, and other deliverables.

“Being able to experiment with existing technology to evaluate design tradeoffs and test a new system before ever bending metal is a game-changer,” Cepak said. “AFSOC is evolving and experimenting in a smart way to reduce technical risk and deliver capability to the field more rapidly and efficiently than before.”

According to Trantham, while the MAC project demonstrates rapid capability development for AFSOC, the Air Force and the Total Force will also benefit.

“We believe MAC will be able to be used by our sister services, allies, and partners on various C-130 platforms,” he said. “Further, expanding the operational use of an amphibious aircraft alongside other innovative tools will provide even more complex dilemmas in future battlespaces for our strategic competitors.”

Thursday, August 12th, 2021

Bell and Team Invictus are combining industry-leading technology with digital processes to improve manufacturing, testing, and integration schedules to deliver a high-performance attack and reconnaissance aircraft

Fort Worth, Texas (August 11, 2021) – Bell Textron Inc., a Textron Inc. (NYSE: TXT) company, has released new data on the build and testing for the Bell 360 Invictus competitive prototype. The Bell 360 program is rapidly progressing through manufacturing, assembly, components testing, and systems integration work for the U.S. Army’s Future Attack Reconnaissance Aircraft (FARA) program. The team has completed multiple design and risk reviews with the Army and is on schedule for all program requirements. The Bell 360, a low-risk, high-speed platform with proven technology and inherently reliable designs, will deliver soldiers transformational operational capabilities at an affordable cost.

“This team is achieving great results responding to requirements, reducing programmatic risk, and delivering state-of-the-art capabilities for the Army,” said Chris Gehler, vice president and program director for the Bell 360 Invictus. “We are combining Bell’s unique knowledge of the demands placed on scout aircraft with engineering and technical expertise to give the Army a weapon system to dominate attack reconnaissance missions for decades to come.”

Since beginning the build in late 2020, Bell has made significant progress on the Bell 360 Invictus fuselage, main rotor blades, gearbox assembly, cases, and other high-value components. By implementing a design-as-built methodology that digitally connects the entire program throughout its lifecycle, Bell has increased its ability to collaborate in real-time with program partners and the Army. This method accelerates decision-making among distributed teams using a common, secure data environment that creates a singular source of data for the program leading to reduced assembly, rework time and cost.   

Along with assembling the Bell 360 Invictus, high-value components such as the main rotor gearbox, driveshafts and couplings are being tested at Bell’s Drive Systems Test Lab (DSTL). The DSTL is used to carry out risk-reduction efforts that ensure the program has accurate and verified data to qualify components in advance of flight test. 

A new FARA-specific Systems Integration Lab (SIL) is also operational at Bell. This facility allows Bell to integrate flight-critical components, software, and mission systems for testing, verification, and validation of functionality before they take flight on an actual aircraft. This approach reduces technical risk and aids in the safe, rapid, and efficient execution of flight test program.

“The Bell 360 Invictus is an exciting aircraft that brings sophisticated digital systems together in a high-speed, reliable, maintainable vehicle for austere environments around the world,” said Jayme Gonzalez, program manager, Bell 360 Invictus. “The Bell 360 offers the Army the ability to modernize using simplified and inherently reliable designs to reduce costs and deliver enhanced effectiveness for the Army.”
