The Static Thrust Characterization Of The Quatra Aerrow Q100xl Engine For Flight Performance Prediction Of The 1/3-Scaled Cessna 172p Model, Joon Fui Ho
Master's Theses - Daytona Beach
The purpose of this research is to predict the thrust as a function of forward flight velocity required for the one-third-scaled Cessna 172P. This model was designed to verify scaling laws. Therefore, it is important that it be aerodynamically scaled and that it have similar thrust characteristic as that of the full scale Cessna 172P. Several propellers and two Quatra Aerrow Q100XL two-cycle engines were acquired for this research project. Three propellers were selected to undergo a series of static thrust testing. The measured static thrust was then used to predict the flight performance of each tested propellers with the …
Investigation Into The Adaptation Of A Steam Injector For Use On A Liquid Rocket Engine, Charles B. Mcfarland
Investigation Into The Adaptation Of A Steam Injector For Use On A Liquid Rocket Engine, Charles B. Mcfarland
Theses and Dissertations
This thesis investigated the properties of a steam injector to see if the concept might be suitable for use on a liquid rocket engine. A steam injector is a device developed in the 1850's to inject feedwater into the boiler on a steam locomotive without any moving parts. The injectors uses a small portion of the steam generated in the boiler to increase the pressure of the feedwater to a level high than the pressure in the boiler. Previous experiments claim that condensation of steam to water was necessary for an injector to work. This experiment tested injection without condensation …
