The one dimension computational model of a sequential injection engine, which runs on compressed natural gas (CNG) with spark ignition, is developed for this study, to simulate the performance of gas flow pressure profile, under various speed conditions. The computational model is used to simulate and study of the steady state and transient processes of the intake manifold. The sequential injec...

Abstract A multi-component aerodynamic test for an airframe-engine integrated scramjet vehicle model was conducted in the free-piston shock tunnel HIEST. free-flight force measurement technique applied to named MoDKI. new method using multiple piezoelectric accelerometers developed based on overdetermined system analysis. Its unique features are following: (1) The accelerometer’s mounting locat...
