Effect of nozzle and vertical-tail variables on the performance of a 3-surface F-15 model at transonic Mach numbers [PDF]

open access: yes
An investigation was conducted in the Langley 16 foot transonic tunnel to determine the longitudinal aerodynamic characteristics of twin two dimensional nozzles and twin baseline axisymmetric nozzles installed on a fully metric 0.047 scale model of the F-

Solid rocket booster internal flow analysis by highly accurate adaptive computational methods [PDF]

open access: yes
The primary objective of this project was to develop an adaptive finite element flow solver for simulating internal flows in the solid rocket booster. Described here is a unique flow simulator code for analyzing highly complex flow phenomena in the solid

A study of nozzle and ejector flow problems by the method of integral relations [PDF]

open access: yes
The application of the method of integral relations to nozzle and ejector flow problems was examined. For nozzle flow problems, the general formulation is that the approaching flow may be rotational.

Airframe/propulsion integration characteristics at transonic speeds [PDF]

open access: yes
The aerodynamic characteristics for both single and twin-engine high-performance aircraft are significantly affected by shock induced flow interactions as well as other local flow interference effects which usually occur at transonic speeds.

Computation of supersonic jet mixing noise for an axisymmetric CD nozzle using k-epsilon turbulence model [PDF]

open access: yes
The turbulent mixing noise of a supersonic jet is calculated for a round convergent-divergent nozzle at the design pressure ratio. Aerodynamic computations are performed using the PARC code with a k-epsilon turbulence model.
