NUMEROUS AIRCRAFT ACCIDENTS HAVE OCCURED DURING TAKEOFF AND LANDING DUE TO THE STRONG AND UNEXPECTED WINDS DIVERGING FROM A MICROBURST OUTFLOW. EXTENSIVE RESEARCH HAS INDICATEDTHAT IT IS POSSIBLE TO DETECT SUCH WINDS BY MEANS OF A DOPPLER WEATHER RADAR. A LOGICAL RADAR CANDIDATE IS THE UNIT CARRIED BY ALL AIR TRANSPORTS. A PROBLEM WITH THE USE OF SUCH INSTALLED RADARS IS THEIR LOWPRF (PULSE REPETI ...

A PROGRAM OF RESEARCH IS PROPOSED THAT WILL REVIEW THE RELEVANT LITERATURE ON RECENT DEVELOPMENTS IN BOUNDARY LAYERCONTROL IN HIGH-SPEED ENGINE INLETS. OF PARTICULAR INTERESTWILL BE INLETS INTENDED TO OPERATE AT FLIGHT MACH NUMBERS ABOVE 3.0 WHERE VISCOUS EFFECTS DOMINATE THE BEHAVIOR OF THEINTERNAL FLOW. THE OBJECTIVE OF THE PHASE I EFFORT IS TO DETERMINE THE FEASIBILITY OF USING INNOVATIVE BOUND ...

MANNED LUNAR BASES WILL REQUIRE COOLING FOR DEHUMIDIFICATION(ABOUT 40 DEGREES FAHRENHEIT) AND HABITAT (60 DEGREES FAHRENHEIT). THE BACKGROUND TEMPERATURE FOR HEAT REJECTION IS 125 DEGREES FAHRENHEIT, REQUIRING REJECT TEMPERATURES OF 180 DEGREES FAHRENHEIT OR ABOVE. WASTE HEAT WILL BE AVAILABLE FROM THE POWER-GENERATING SYSTEM ABOVE 500K (440 DEGREES FAHRENHEIT). COMPLEX-COMPOUND SORPTION CYCLES CA ...

THE DESIGN OF A NOVEL OPEN CAVITY ANTI-RESONANCE TECHNIQUE WILL BE CARRIED OUT UNDER THE INITIAL PORTIONS OF THE PHASE I EFFORT. DETAILED DESIGN AND FABRICATION OF THE AIRCRAFT MODIFICATIONS TO BE PERFORMED ON THE KUIPER AIRBORNE OBSERVATORY WILL BE CARRIED OUT BY THE GOVERNMENT. THE CONTRACTOR WILL PERFORM A FULL-SCALE FLIGHT EXPERIMENT USINGTHE INNOVATIVE SHEAR LAYER CONTROL FAIRING IN CONJUNCTI ...

Spatial uniformity within combustion devices, especially circumferential, is extremely important to the reliability and durability of a liquid rocket engine. Conventional combustion diagnostics, e.g. pressure and thrust, characterize global engine behavior, but provide no direct information about thermal and species distributions across the engine. Sierra Engineering has shown that exhaust plume m ...

Accurate navigation is a crucial part of both robotic and crewed exploration of other worlds. For missions to the surfaces of Mars and the Moon, mission planners will require increasingly autonomous guidance systems that support fast, efficient, and agile surface route planning. These navigation systems will rely on access to accurate and regularly updated maps of surface landmarks. In a recent pi ...

AeroMancer Technologies proposes to develop an 3D Airspeed Backscatter Correlation (3D-ABC) lidar velocimeter for in-flight boundary layer flow visualization and airspeed measurement in spatially and temporally resolved 3D flow fields using a rugged, eye-safe, daytime-capable, reliable Infrared (IR) optical device. AeroMancerrsquo;s technique for measuring 3-component spatially and temporally reso ...

This sound, low risk and exciting proposal aims at developing technology for the fundamental accurate modeling and data processing needs of future autonomous operation and system design within the paradigm of the digital twin. Truly autonomous operation of power systems (e.g. turbo-electric distributed propulsion aircrafts) cannot be scripted. An intelligent system capable of self-healing and mana ...
