In aerospace medicine, attention focuses on the effects of the loss of gravitational pull on the body. The more fundamental question involved is the basic physiology of anti-gravity mechanisms upon the body. From this viewpoint, the entire spectrum of the consequences of weightlessness may be seen. Then evidence affirming the broad concept of sensory deprivation in general, and anti-gravity dep...

Gelled fuels have promising applications in the aerospace field. Higher density and calorific value can be achieved with addition of energetic metal particles to gelled fuels, which also effectively improve combustion efficiency fuel thus enhance engine performance. However, make rheological properties more complex, introduces difficulties regarding their atomization combustion. In order invest...

this paper is the representation of the computational and experimental methods of a new injector nozzle for a sequential port injection cng engine. the objective of this study was to review the previous research in the development of gaseous fuel injector for port injection cng engine converted from diesel engine. next, a simulation of the fuel flow of the new injector nozzle was made using flu...

NASA is investigating passive wireless sensor technology to reduce instrumentation mass and volume in ground testing, air flight, and space exploration applications. Vehicle health monitoring systems (VHMS) are desired on all aerospace programs to ensure the safety of the crew and the vehicles. Pervasive passive wireless sensor networks facilitate VHMS on aerospace vehicles. Future wireless sen...

Turbochargers are most widely used in automotive, marine and locomotive applications with diesel engines. To increase the engine performance nowadays, in aerospace applications also turbochargers are used. Mostly the turbocharger rotors are commonly supported over the fluid film bearings. With the operation, lubricant properties continuously alter leading to different load bearing capacities. T...

nowadays biodiesel is receiving more attention as a most important renewable energy for using in diesel engines. inthis research, the application of response surface methodology (rsm) was highlighted to investigate the effects of biodiesel-diesel blends (b0, b20, b50 and b100), engine operating parameters (engine load and  speed) on co2 emission of a diesel engine. the experiments were conducte...

This paper described some mechanical properties of aluminum alloy using agro-waste materials such as sawdust, groundnut shell, and eggshell. The sand-casting method was adopted to produce the with 5, 15, 25, 35% wt. additives. microstructure various samples produced after quenched in water, palm oil, engine oil examined while hardness were determined. result obtained shows that values increased...

NASA Glenn Research Center, in collaboration with the aerospace industry and academia, has begun the development of technology for a future hybrid-wing body electric airplane with a turboelectric distributed propulsion (TeDP) system. It is essential to design a subscale system to emulate the TeDP power grid, which would enable rapid analysis and demonstration of the proof-of-concept of the TeDP...

Abstract In the frame of RETALT (RETro propulsion Assisted Landing Technologies) project, aerodynamics reusable launch vehicles reentering atmosphere and descending landing with aid retro are studied. particular, series wind tunnel tests performed to assess aerodynamic properties such a vehicle in various flight phases from hypersonic supersonic re-entry down subsonic conditions at touch down. ...
