Numerical Modeling and Performance Analysis of a Scramjet Engine with a Controllable Waverider Inlet Design

摘要

A method for automatically determining performance characteristics of a scramjet engine uses a 1-dimensional approximation that includes obtaining a first set of environmental conditions defining freestream conditions; generating inlet outflow conditions by evaluating a change in flow from the freestream conditions across the inlet; generating isolator outflow conditions by modeling change in flow from the inlet outflow conditions across the isolator; generating combustor outflow conditions by modeling change in flow from the isolator outflow conditions across the combustor; and generating nozzle outflow conditions by modeling change in flow from combustor outflow conditions across the nozzle.
