EFFECTS OF XLR-99 ENGINE NOZZLE OPTIMIZATION ON MAXIMUM ENGINE PERFORMANCE

Abstract

The mission of the X-15 aircraft engine requires that the engine operate at 40,000 to 250,000 feet altitude. Since nozzle optimization is presently at 17,000 feet, methods of increasing engine performance by optimization of the nozzle to higher altitudes were studied. Theoretical results indicate that optimization can be achieved at 40,000 feet by extending the present nozzle 18 inches. The exit area of this nozzle would still be within the limits imposed by the contour of the X-15 tail section. Optimization over 40,000 feet would probably require major design changes.
