Vertical Take Off and Landing (VTOL) Aircraft with Vectored Thrust for Control and Continuously Variable Pitch Attitude in Hover

Most fixed-wing VTOL unmanned aerial vehicles (UAVs) take off vertically, then transition to horizontal flight. This is a new type of UAV that has unique capability. It can vary its hover position from “nose up”...

Exhaust Plume Analyzer

Exhaust plumes emanating from smoke stacks at power plants or other industrial facilities can have adverse impacts on local aviation during periods of calm winds. Adverse impacts can be exacerbated if the temperature is low or the atmosphere is unstable. While low oxygen concentrations and elevated temperatures inside the...

Device for Providing Real-Time Rotorcraft Noise Abatement Information

Rotorcraft typically operate near the ground throughout the duration of the operation. For this reason, military rotorcraft are vulnerable to acoustic detection, and public acceptance of civil rotorcraft is limited by annoyance caused by rotor noise radiation. The purpose of...

Automated Conflict Resolution for Air Traffic Control (AAC) Versions 1 and 2

A conflict resolution algorithm that can provide automated separation assurance for the next-generation air traffic control system has been developed. The algorithm generates resolution trajectories that can be sent to the aircraft from a ground-based system via a data...

Facility Focus: NASA's Lyndon B. Johnson Space Center

NASA's Johnson Space Center (JSC) has been a leader in human space exploration for more than half a century. Established in 1961 in Houston, TX as the Manned Spacecraft Center, the center...

Question of the Week : Aerospace
Will Urban Air Mobility ‘Take Off?'

A Tech Briefs TV video demonstrates NASA’s rotary-wing “air taxi” concept. The vehicles, in theory, have the capacity for vertical take-off and landing, eliminating the need for long runways.

NASA hopes the air taxi will support Urban Air Mobility, a system that combines onboard/ground-piloted...

Question of the Week : Aerospace
How Strong is the ‘Ionic Wind?’

MIT has built the first-ever plane with no moving parts. Instead of turbine blades, propellers, and fans, the aircraft relies on an “ionic wind” — a silent but strong flow of ions, produced onboard, which generates enough thrust to propel the plane over a sustained, steady flight.

“This has...

Multi-Axis Motion Controller Accelerates Gear Testing

Materials testing and characterization is often a lengthy process. It can take more than a year and billions of testing cycles for a manufacturer to characterize the properties of a new...

Shape Memory Alloy Rock Splitters (SMARS)

Glenn's revolutionary Shape Memory Alloy Rock Splitters (SMARS) device is fabricated from nickel-titanium-halfnium (NiTiHf), nickel-titanium-zirconium compositions, or a combination. These compositions contain a secondary, nanometer-sized precipitate phase that is produced through processes of...

Sensor Combination Detects People by Smell

Trained rescue dogs are the best disaster workers — their sensitive noses help them track down people buried by earthquakes or avalanches. But dogs need breaks. A new measuring device is always...

Optimetric Measurements Over Coherent Free-Space Optical Communication

High-precision ranging (optimetric) instruments are highly desired for both space navigation and communications as well as gravitational-based science missions. Traditionally, these measurements are made with instruments solely dedicated to ranging (i.e. Doppler shift of a...

Variable-Pitch Turbine Blades

Gas turbine blades of conventional rotorcraft turboshaft engines are optimized to operate at nearly a fixed speed and a fixed incidence angle. If the operating condition of the engine changes, then the flow...

Plane Flies with No Moving Parts

Since the first airplane took flight, virtually every aircraft has flown with the help of moving parts such as propellers, turbine blades, or fans that produce a persistent, whining buzz. MIT has built the...
