FlexSys Featured in Professional Boatbuilder Magazine

The October/November 2016 issue Professional BoatBuilder magazine featured FlexSys technology in an article describing the ways that new technologies in aviation can be used in the boatbuilding industry. In particular, the author notes that the wing morphing technology used in aerospace applications can be applied to trim tab planes on boat hulls, which can control attitude of the hull with less sacrifice in drag than conventional trim tabs. From the article:

On some boats, rigid trim-tab planes hang off the transom below the waterline; on others, the tabs are recessed into the hull bottom, but when fully retracted they typically are flush with the adjacent surface, or slightly above parallel when transom hung. A flexible hull surface that could become concave might be more fuel efficient in producing bow-down attitude than dropping a recessed or transom-mounted trim plane into the water below the hull.

Aviation Partners-FlexSys Goes Public With Morphing Wing Technology Demonstrator

After several years of technology development and full-scale flight testing, the engineers at FlexSys Inc. in Ann Arbor have crafted a new FlexFoil™ morphing technology demonstrator wing that was unveiled at the 2016 National Business Aviation Association (NBAA) convention in Orlando, FL. The effort is in support of their new joint venture with Aviation Partners Inc., Aviation Partners FlexSys (APF) and demonstrates that the technology is ready for application-specific design for commercial and military use.

Aviation Partners Inc. provided the team at FlexSys a wing that was custom-made to be retrofitted with FlexFoil™ technology. The resulting demonstrator wing has 4 active control surfaces that enable high-lift, roll-control, load alleviation, and leading edge droop and de-icing.  It highlights the smooth camber (curvature) change possible with the FlexFoil™ technology. Each of the 4 surfaces provide performance benefits, whether it be through drag reduction, weight reduction, load control, or improved lift distribution.

FlexSys wins JEC Composites Innovation Award in Design

 

PRESS RELEASE

JEC Group, the world’s largest organization exclusively dedicated to the composites industry, has announced the ten winners of its prestigious 2016 JEC Americas Innovation Awards program. The ceremony will take place during the 5 th annual JEC Americas Composites Show and Conferences at the Georgia World Congress Center in Atlanta.

Category: DESIGN
Winner: FlexSys Inc. (USA)
Name of Product or Process: Compliant design technology and software for product designers of the future

Description: By using compliant design expertise and methods, FlexSys was able to design a single-piece wiper arm and blade that costs less and both outlasts and outperforms traditional metal assemblies. A composite thermoplastic of 30%-glass-filled PBT was determined to have the required properties and characteristics to meet the demands and provide the necessary strength/stiffness ratio. The single-piece moulded design eliminates 11 parts along with the associated assembly, weighs half as much, and costs only 1/3 as much as the legacy design.

Unlike the traditional hinged blade, this wiper provides constant spring pressure to the blade through each of its arms. However, the difficulty in development was that current 3D modelling programs were not up to the task, as they design using rigid members and linkages. In compliant design, the elasticity of materials must be embraced and used to create motion. To surmount this obstacle, FlexSys is developing unique software called FlexWorks™, with the help of a grant from the National Science Foundation.

This software allows the input of desired motions and magnitudes, and will run through thousands of iterations to find one to most closely fit the given criteria. It considers the maximum stress/strain capability of the material in each iteration so as not to exceed it. The output provides the required thickness variation throughout each bending member. It will also show the new compliant mechanism in motion, bending, and displaying a stress analysis. The final design can be changed in the edit mode and re-evaluated, then saved in a file to 3D print or import to Solidworks, Ansys, etc. FlexSys believes the software could eventually become a module available in 3D modelling programs. The first ever public view and alpha release of the software will be available in the JEC Atlanta demo zone.

The advancement of composite injection moulding materials will fuel the future of compliant structures. Additives such as carbon fibres and nanotechnologies can increase the strength/flexibility ratio, allowing for higher load applications with greater fatigue-free travel. More compliant design concepts can be seen in the demo zone, including applications in the automotive, medical, robotics and prosthetics fields.

Aviation Partner's Joe Clark was honored by the National Business Aviation Association with the 2015 Meritorious Aviation Service Award for his contributions to Aviation. The award was presented at the 2015 NBAA Conference on November 17 in Las Vegas, NV where FlexSys' joint venture with Aviation Partners was also announced.

This video was shown at the awards presentation featuring several living legends of aviation whose lives have been touched by Joe Clark.

From NBAA's press release:

Aerospace innovator Joe Clark is the chairman and CEO of Aviation Partners, Inc. (API) and chairman of the Aviation Partners Boeing joint venture. He is widely recognized as a pioneer in the fuel-saving and performance-enhancing technology of blended winglets.

Together, with entrepreneur Dennis Washington, Clark cofounded API in 1991 to develop and market winglet modifications for business and commercial aircraft. In its 25 years, API has supplied blended winglets to thousands of aircraft, including the Gulfstream II, Boeing Business Jet, several types of Boeing airliners, the Hawker 800 and 800XP and several Falcon Jet models. Worldwide, API’s winglets have saved an estimated 5 billion gallons of fuel.

“Joe Clark is an aviation visionary and a true entrepreneur,” said NBAA President and CEO Ed Bolen. “In founding API, he brought together the brightest minds in aerospace engineering and helped develop advanced technology to improve aircraft performance and minimize aviation’s impact on the environment.”

Clark’s passion for aviation began while still in college, when he started flying lessons. In 1964, a friend, Clay Lacy, invited Clark to travel to the Reno Air Races aboard a Learjet. In 1966, Clark founded Jet Air, the first Learjet dealership in the Northwest and was named vice president of sales for aircraft modification specialist Raisbeck Engineering. In 1981, he cofounded regional carrier Horizon Air, which later became part of Alaska Airlines. In 1986, he founded Avstar, Inc., a system to market business aircraft previously used for military training.

When Clark founded API, the company’s first project was developing blended winglet technology for the Gulfstream II, which increased the aircraft’s range, speed and fuel efficiency.

“We’re proud to recognize Joe Clark with NBAA’s highest honor, the Meritorious Service to Aviation Award,” said Bolen. “Like past recipients, his achievements have advanced the technology of flight.”

Aviation Partners FlexSys to Commercialize Wing Morphing Technology

Las Vegas, November 16, 2015… On the eve of the NBAA Business Aviation Convention & Exhibition two world leaders, one in advanced winglet technology and the other in shape-adaptive structures, announce they are entering into a joint venture. Seattle, Washington based Aviation Partners, Inc. is in the final stages of forming a JV with FlexSys, Inc. of Ann Arbor, Michigan. The new company, Aviation Partners FlexSys (APF), is being founded to commercialize the patented ‘wing morphing’ technology which FlexSys, Inc. has been working on since its formation in 2000. FlexSys’ FlexFoil™ variable geometry control surface mechanisms were recently test flown on a Gulfstream business jet.

“With over 6,300 shipsets of Blended Winglets in-service Aviation Partners has a long history of success when it comes to certification and marketing of performance improvements for business and commercial aviation,” said Joe Clark, API Founder and CEO, “We are excited to write a new chapter in aerodynamic design through the formation of this JV with Dr. Kota and his FlexSys team.” 

FlexFoil™ variable geometry surface mechanisms leverage the natural flexibility of aerospace-grade materials to continuously reshape the external form. The proprietary internal joint-less skeletal configuration of the system is optimized to achieve desired aerodynamic shapes on demand when actuated, while also meeting the aircraft design requirements of: strength, lightweight, high fatigue life, reliability and low maintenance.

Importantly, the multifunctional seamless surface is uniquely capable of delivering desired camber change and span-wise twist at high rates for drag reduction, load alleviation, noise reduction, etc. 

“Replacing conventional multi-jointed flaps and other control surfaces with smooth seamless surfaces has been an elusive goal for the aerospace industry for decades. After 15 years of R&D, and successful flight-testing, the FlexFoil™ variable geometry control surface mechanism ushers in a new frontier in aircraft design,” said Sridhar Kota, Founder and President of FlexSys, “We are thrilled to enter into a joint venture with Aviation Partners who, under the dynamic leadership of Joe Clark, has a proven track record of transforming innovative ideas into successful aviation products with benefits to the global marketplace.” 

Commercial opportunities being studied by APF for this revolutionary technology in the near future include flight controls, leading/trailing edge devices, anti-icing and active winglets. APF plans to offer the technology for both retrofit and new production applications. An example of the FlexFoil™ test article, as flown beneath White Knight, can be seen in-operation at the API booth (#C8113) during NBAA.

FlexSys Receives 2015 Tibbetts SBIR Award

FlexSys has been honored with a Tibbetts SBIR (Small Business Innovation Research) Award for Companies for its work with the US Small Business Association to get FlexSys technology in the air.

 
 
Changing the course of aviation history through SBIR is just what FlexSys, Inc. accomplished when it flew the world’s first shape changing aircraft wing. In 1998, company founder and the inventor of FlexFoilTM Variable Geometry Control Surfaces, Dr. Sridhar Kota received an Air Force SBIR Phase I contract to prototype and test an Adaptive Compliant Wing and in 2000, Kota received an Air Force SBIR Phase II contract to further demonstrate and test compliant design of shape-changing control surfaces. FlexSys was founded in 2001 to build and test various structural and wind tunnel models and encouraged by continuing success, the Air Force Research Laboratory (AFRL) provided enhancement funds under an SBIR Phase II. In 2006, FlexSys designed and fabricated a prototype wing section and affixed it to the underside of White Knight aircraft for extensive flight tests, which showed fuel efficiency improvements, and in 2009 AFRL funded an SBIR Phase III program to modify a Gulfstream-III research aircraft, replacing its conventional flaps with a FlexFoil™ Adaptive Compliant Trailing Edge (ACTE). NASA joined the AFRL-FlexSys team in 2009 for the final phase of the technology maturation, the flight test of ACTE.

On November 6, 2014, FlexSys, AFRL, and NASA achieved a milestone that the aviation industry has been attempting to reach for 50 years - FlexfoilTM ACTE technology finally proved that a practical, lightweight, seamless shape-morphing wing is possible. This invention is expected to save 4-12% in fuel costs in an industry that spends over $200 billion yearly on jet fuel, and where improvements of a mere 1% are considered significant. FlexFoil™ technology also eliminates gaps that produce airframe noise and, according to NASA, it is expected to reduce aircraft noise by 40%. 

Funded by the Air Force SBIR program – (Phase I-1998, Phase 2 -2001-08, and Phase 3 -2009- 2015), totaling nearly $20 million, the technology has now matured to TRL 6+ ushering in a new frontier in aviation and enabling significant reductions in fuel burned, emissions, cost and noise. The company now has 7 full time and 5 part time employees with plans to hire two more fulltime employees this year. Dr. Sridhar Kota is also a Professor of Mechanical Engineering at the University of Michigan – Ann Arbor. FlexSys has actively engaged UM faculty through research contracts, provided part-time and full-time positions to UM students and has also licensed related technologies from UM.

ACTE Featured in Professional Pilot Magazine and More

The FlexSys/USAF/NASA Active Compliant Trailing Edge (ACTE) project has been receiving a lot of press lately. We have compiled some of our favorites that best summarize the project.


Professional Pilot Magazine, billed as the magazine for aviation professionals, has one of the most comprehensive features. Beyond explaining the ACTE project, Professional Pilot examines the FlexSys technology behind it.

Like Wilbur Wright and others, FlexSys Founder & CEO Dr Sridhar Kota, a mechanical engineer and inventor of FlexFoil, has long had an appreciation for nature. According to Dr. Kota, "Nature is filled with strong, elegant, shape-shifting mechanisms." In nature, examples of designs that are flexible and yet strong include the wings of birds, the trunk of an elephant or tree branches. By contrast, in human technology most artifacts that are strong are also rigid and stiff with multiple parts and complex assemblies.
