Rocket Motor Design Could Boost Small Satellite Missions

Artists concept of a CubeSat onboard propulsion system. (Photo: Inside Out Visuals) Researchers at Los Alamos National Laboratory have developed a rocket motor concept that could be used to power CubeSat low-cost satellites. The Los Alamos team recently tested a six-motor CubeSat-compatible propulsion array with tremendous success.

Morphing Wing Could Enable More Efficient Manufacturing and Flight

The entire shape of the wing can be changed by activating two small motors that apply a twisting pressure to each wingtip. (Photo: Kenneth Cheung/NASA) A new morphing wing architecture could greatly simplify the manufacturing process and reduce fuel consumption of aircraft by improving the wing’s aerodynamics, as well as improving its agility. The wing consists of a system of tiny, lightweight subunits that could be assembled by a team of small, specialized robots, and ultimately could be used to build the entire airframe. The wing would be covered by a “skin” made of overlapping pieces that might resemble scales or feathers.

Spherical Motor Eliminates Robot’s Mechanical Drive System

The spherical induction motor eliminates the robot's mechanical drive system. The SIMbot robot features an elegant motor with just one moving part: the ball. The only other active moving part of the robot is the body itself. A spherical induction motor (SIM) eliminates the mechanical drive system and can move the ball in any direction using only electronic controls. These movements keep SIMbot’s body balanced atop the ball.

New Steel Enables Better Electric Motors

Jun Cui of Iowa State University’s Ames Laboratory works with a metal spinner, which rapidly solidifies metal into thin ribbons. (Photo by Christopher Gannon) In order to make plug-in electric vehicles as affordable and convenient as internal-combustion cars, their motors must be smaller, lighter, more powerful, and more cost-effective. A research team is working to develop motors with the stator core (a non-rotating, magnetic part) manufactured with thin layers of a new “electrical steel.”

Elastomer Enables Soft Flapping Robotic Wings

Researchers have discovered a new resonance phenomenon in a dielectric elastomer rotary joint that can make the artificial joint bend up and down, like a flapping wing. The new phenomenon makes the dielectric elastomer joint a good candidate for creating a soft and lightweight flapping wing for robotic birds, which would be more efficient than bird wings based on electrical motors due to the higher energy conversion efficiency of the dielectric elastomer.

Alcohol Ignition Lock Could Prevent Drunk Driving

If every new car made in the United States had a built-in blood alcohol level tester that prevented impaired drivers from driving the vehicle, how many lives could be saved, injuries prevented, and injury-related dollars left unspent? Researchers at the University of Michigan studied the impact of installing these alcohol ignition interlock devices in all newly purchased vehicles over a 15-year period.

Aircraft with Hybrid Engine Can Recharge in Flight

Researchers from the University of Cambridge, in association with Boeing, have successfully tested the first aircraft to be powered by a parallel hybrid-electric propulsion system, where an electric motor and gas engine work together to drive the propeller. The demonstrator aircraft uses up to 30% less fuel than a comparable plane with a gas-only engine. The aircraft is also able to recharge its batteries in flight, the first time this has been achieved.
