Study Could Help Aircraft Avoid Dynamic Stall

University of Illinois researchers are studying the physics of dynamic stall so that it can be used beneficially and reliably by aircraft. The problem has been studied at low speeds but at higher speeds, the process becomes significantly disorganized and difficult to understand.

Cartilage-Like Material Enables Structural Battery

A structural battery prototype incorporates a cartilage-like material to make the batteries highly durable and easy to shape. The idea behind structural batteries is to store energy in structural components like the wing of a drone.

NIF Experiments Support Warhead Life Extension

It was a normal morning for design physicist Madison Martin at Lawrence Livermore National Laboratory (LLNL). At 7:45 a.m., she settled into her classified workstation with a cup of tea to check the results of a numerical calculation she ran overnight. If the calculations proved correct, the experiment she was designing on the National Ignition Facility (NIF) would deliver the data her colleagues needed to verify that a refurbished nuclear warhead would perform as expected.

Discovery Could Lead to Munitions That Go Further, Much Faster

Researchers from the U.S. Army and top universities discovered a new way to get more energy out of energetic materials containing aluminum, common in battlefield systems, by igniting aluminum micron powders coated with graphene oxide. This discovery coincides with the one of the Army's modernization priorities: Long Range Precision Fires. This research could lead to enhanced energetic performance of metal powders as propellant/explosive ingredients in the Army's munitions.

Navy Launches Virtual Training Tech for Aircraft Carrier Flight Deck Crews

One of the most dangerous environments in the U.S. Navy is the deck of an aircraft carrier. Catapult systems that can remove limbs, furious engines, whipping propellers, and high winds create a hectic environment. The driving force behind all of these activities is helping a pilot land an aircraft on a short slab of pitching steel in the middle of the ocean. Although pilots are the stars of the show, they could not accomplish their missions without the support of flight deck crews, who are responsible for safely launching and recovering aircraft.

Porous and Stiff Material for Aircraft Lightweighting

Researchers have developed and manufactured a family of architectures that maximizes the stiffness of porous, lightweight materials. 3D printing and other additive production techniques make it possible to manufacture materials with internal structures of previously unimaginable complexity. Achieving this requires that the internal structures be intelligently organized for maximum efficiency.

The stiffness in the material’s interior is achieved through plate-lattices rather than trusses. These structures that are up to three times stiffer than truss-lattices of the same weight and volume.

Foldable Drone Flies Through Narrow Holes

A new drone was developed that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters, such as inspecting a damaged building after an earthquake or during a fire.

The autonomous, morphing drone has onboard perception and control systems, enabling it to maneuver in tight spaces and guarantee a stable flight at all times.

NASA Experiments Fly on Virgin Galactic Spacecraft

Virgin Galactic’s SpaceShipTwo successfully flew to suborbital space last month with four NASA-supported technology payloads onboard. NASA’s Flight Opportunities Program purchased flight services, the accommodation, and ride from Virgin Galactic for the payloads. During the flight, the payloads collected valuable data needed to mature the technologies for use on future missions.

Improving Performance of Hybrid-Electric Aircraft

Although hybrid-electric cars are becoming commonplace, similar technology applied to airplanes comes with significantly different challenges. University of Illinois aerospace engineers are addressing some of them toward the development of a more sustainable alternative to fossil fuels to power airplanes.

Virtual Runway, Real Pilot Practice

When a plane overshoots the final approach, often the pilot’s natural — and dangerous — instinct is to pitch the aircraft up to slow down and land. It’s one of the leading causes of accidents, especially with small airplanes. But what if that same mistake happened at 5,000 feet instead?
