AFRL camber morphing wing takes flight
Smooth composite skin enables active re-contour of up to 6% and fuel savings of 10%.
The Air Force Research Laboratory (AFRL, Wright-Patterson Air Force Base, Ohio, U.S.) recently completed the successful flight demonstration of a game-changing camber morphing wing technology that could significantly increase aircraft range and performance.
The AFRL-developed Variable Camber Compliant Wing (VCCW) is capable of changing shape to improve aerodynamic performance and morph itself to various flight conditions and missions. Wing camber, or the shape of a wing surface, is a fundamental element of aerodynamic flight. Conventional wings with discrete hinged control surfaces have greater drag, whereas wings with a smooth camber are efficient and maneuverable. The ability to morph the wing according to aerodynamic conditions would give an aircraft increased lift when needed without a weight penalty — typically at takeoff and landing — and greater fuel-efficiency and maneuverability when in flight.
This flight experiment demonstrated the second iteration of the VCCW, a smaller, more compact version than the first, which was used primarily in wind tunnel experiments. This eight-foot wing was designed to be flown on a commercial-off-the-shelf remotely controlled aircraft, simulating an unmanned air vehicle. During the series of flights, held in September and October 2019, the wing was flown at low speeds, completing a number of maneuvers and demonstrating active shape control for optimized drag reduction and increased agility.
Single-piece, composite skin
The VCCW features smooth and continuous skin construction, which not only reduces noise by eliminating sharp surfaces and gaps, but improves aerodynamic performance as well. According to Dr. James Joo, AFRL Advanced Structural Concepts team lead and VCCW program manager, the improved aerodynamics translates into potentially significant fuel savings.
“Early estimates show VCCW technology saving aircraft fuel consumption by 10 percent,” said Joo. “This was one of our main goals, and it fits the Air Force’s efforts to reduce overall energy costs.”
According to a Dec 2019 article in TechBriefs.com:
“The wing can actively re-contour the airfoil camber up to 6% and the entire skin is seamless, continuous, and made of a single-piece, non-stretchable composite skin. Smooth conformal shape of the wing is attained by distributed elastic deformation from the underlying compliant mechanism and 3D shape change is also capable through variation of camber along the spanwise direction using a distributed actuation system along the span. Single actuation control for both leading and trailing edge deflection is another very unique aspect of VCCW compared to previous technologies. It was fabricated using advanced manufacturing technology enabling a solution that is lightweight, low power, and low cost.”
Advancing flexible wing technology
Jared Neely, AFRL research engineer and designer of the morphing wing, called this demonstration an important step in advancing flexible wing technology for warfighter use.
“The success of this demonstration has given us confidence that this technology can be leveraged to higher-class vehicles, to take advantage of the many benefits this technology can truly offer.”
Joo added that although other research organizations have explored the morphing camber concept, AFRL’s version is unique because it is a true flexible wing without any discrete control surfaces to assist in takeoff and landing. This seamless surface can increase overall range, making it ideal for a variety of long-range platforms. He says the team will continue to refine the concept and look into additional ways it can benefit existing aircraft.
“We are excited about the success of this demonstration,” said Joo. “We are continuing to explore the opportunities that this technology can offer for future Air Force aircraft development.”
Researchers develop carbon nanotube heat shield
A team of researchers from Florida State University is developing a design for for a carbon nanotube-based heat shield for use on satellites, rockets and jet aircraft.

A team of researchers from Florida State University’s High-Performance Materials Institute (HPMI; Tallahassee, Fla., U.S.) is developing a design for for a carbon nanotube-based heat shield for use on satellites, rockets and jet aircraft. Their work is published in the November 2019 edition of the journal CARBON.
The team used sheets of carbon nanotubes (see CW’s primer on nanomaterial types and definitions) to build the heat shields. These sheets, also known as “buckypaper,” were soaked in a phenol resin to create a lightweight, flexible material that reportedly durable enough to protect the body of a rocket or jet from the intense heat it faces while flying.
According to Ayou Hao, a research faculty member at HPMI, existing heat shields are often very thick compared to the base they protect, while this design lets engineers build a very thin shield, like a sort of skin that protects the aircraft and helps support its structure.
After building heat shields of varying thicknesses, the researchers put them through several tests. One test involved applying a flame to the samples to see how they prevented heat from reaching the carbon fiber layer they were meant to protect. After that, the researchers bent the samples to see how strong they remained.
They found the samples with sheets of buckypaper were better than control samples at dispersing heat and keeping it from reaching the base layer. They also stayed strong and flexible compared to control samples made without protective layers of nanotubes. According to the researchers, the flexibility of the nanotubes means the sheets are less vulnerable to cracking at high temperatures compared to ceramics, a typical heat shield material. They are also lighter weight compared to traditional materials.
The project received second place among peer-reviewed posters at the 2019 National Space and Missile Materials Symposium and received third place at the Society for the Advancement of Material and Process Engineering 2019 University Research Symposium.
The project was partially supported by teh U.S. Air Force Office of Scientific Research.

Lockheed Martin delivers Mars 2020 rover aeroshell to launch site
The composite aeroshell for the Mars 2020 rover is, along with the Curiosity rover, the largest built.

The capsule-shaped aeroshell that will protect NASA's Mars 2020 rover was delivered to NASA's Kennedy Space Center in Florida on Dec. 13. Built by Lockheed Martin (Littleton, Colo., U.S.), the aeroshell will encapsulate and protect the Mars 2020 rover during its deep space cruise to Mars, and from the intense heat as the entry system descends through the Martian atmosphere to the surface of Mars.
Because of the large mass and unique entry trajectory profile that could create external temperatures up to 3,800°F (2,093°C), the heat shield uses a tiled Phenolic Impregnated Carbon Ablator (PICA) thermal protection system instead of the Mars heritage Super Lightweight Ablator (SLA) 561V.
This will be the second time PICA has flown on a Mars mission. The first was the Curiosity rover launched in 2011. See CW’s coverage of composites’ role in Curiosity’s design.
“Even though we have the experience of building the nearly identical aeroshell for the Curiosity rover, the almost 15-foot diameter composite structure was just as big a challenge to build and test 10 years later,” says Neil Tice, Mars 2020 aeroshell program manager at Lockheed Martin Space. “We've built every Mars aeroshell entry system for NASA of its 40 years of exploring Mars, so we pulled from that experience to build this important system.”
According to Lockheed Martin, along with the Curiosity mission, this is the largest aeroshell/heat shield ever built for a planetary mission at 4.5 meters (nearly 15 feet) in diameter. In contrast, the aeroshell/heat shield of the InSight lander measured 8.6 feet and Apollo capsule heat shields measured just less than 13 feet.
The backshell and heat shield were transported from Lockheed Martin's Waterton facility in Littleton, Colorado where they were built, to nearby Buckley Air Force Base. They were then loaded onto an Air Force transport plane and flown to NASA's Kennedy Space Center.
Recently, Lockheed Martin integrated the MSL Entry Descent and Landing Instrument (MEDLI2) onto the heat shield and backshell. Provided by NASA's Langley and Ames Research Centers, MEDLI2 will collect temperature and pressure data during the spacecraft's descent through the Martian atmosphere.
The Mars 2020 rover is in testing at NASA's Jet Propulsion Laboratory, Pasadena, Calif., U.S., which manages the Mars 2020 project for the NASA Science Mission Directorate. The mission will launch in July 2020 and land on Mars in February 2021 at the Jezero Crater.
