IMPLICATIONS OF EFFICIENCY ON RANGE AND DESIGN
For fighter aircraft that need high thrust/weight and fly at high speed, it is typical to employ engines with smaller inlet areas and higher thrust per unit mass flow,
The small inlet of one of the F-22
Prandtl-Meyer expansion fan
From Wikipedia, the free encyclopedia
A Prandtl-Meyer expansion fan is a centered expansion process, which turns a supersonic flow around a convex corner. The fan consists of infinite number of Mach waves, diverging from
