Experimental Testbed for 1-MW Turboelectric Distributed Propulsion Aircraft

Researchers at NASA’s Armstrong Flight Research Center are developing a concept aircraft for testing turbo-electric distributed propulsion (TeDP) experiments. TeDP generally involves providing thrust to an aircraft via wing-mounted ducted electric fans, which consist...

Briefs: Mechanical & Fluid Systems

A variable-structure control system designed to enable a fuselage-heavy airplane to recover from spin has been demonstrated in a hand-launched, instrumented model glider airplane (see...

Briefs: Mechanical & Fluid Systems

Small, instrumented, expendable robotic aircraft and projectiles have been proposed for use in scouting for targeted new sites by providing closeup images with ~10-cm resolution,...

Briefs: Physical Sciences

Small instrumented, free-flying (unpowered) rotary aircraft have been proposed for use in gathering scientific data from hazardous or inaccessible terrain on remote planets as well as on Earth. These aircraft...

Personal Cabin Pressure Alarm

Compact instruments, similar in appearance to common personal pagers, have been proposed for warning aircraft crewmembers that cabin air pressure has decreased to a potentially dangerous level. An instrument of this type, called a "personal cabin pressure monitor and warning system" (PCPMWS), implements a warning...
