State-Based Switching Control Strategy with Application to Aeroengine Safety Protection
Publisher: American Society of Civil Engineers
Abstract: This study is concerned with the thrust regulation and safety protection problem for aeroengines, and a state-based switching control strategy is proposed. Specifically, the multiloop switching control framework of aeroengines ...
Scramjet Isolator Shock-Train Leading-Edge Position Modeling Based on Equilibrium Manifold
Publisher: American Society of Civil Engineers
Abstract: A dynamic model showing the relationship between backpressure and shock-train leading edge (STLE) is necessary in the development of a STLE automatic control algorithm. In this research, a nonlinear dynamic model based on ...
Ignition Characteristics of a Liquid-Kerosene-Fueled Scramjet during Air Throttling Combined with a Gas Generator
Publisher: American Society of Civil Engineers
Abstract: The ignition characteristics of a flush wall, liquid-kerosene-fueled scramjet combustor are tested in a directly connected ground test rig. The total temperature and Mach number of the vitiated airflow at the exit of the ...
Effect of Fuel Injection Allocation on the Combustion Characteristics of a Cavity-Strut Model Scramjet
Publisher: American Society of Civil Engineers
Abstract: The cavity-strut supersonic combustion organization method has been found to improve the combustion performance of ethylene in recent studies. In this work, liquid kerosene combustion experiments have been carried out in ...
