The design and performance estimates for the propulsion module for the booster of a TSTO vehicle [PDF]

open access: yes
A NASA study of the propulsion systems for possible low-risk replacements for the Space Shuttle is presented. Results of preliminary studies to define the USAF two-stage-to-orbit (TSTO) concept to deliver 10,000 pounds to low polar orbit are described ...

Experimental analysis and modeling of gas turbine engine performance: Design point and off-design insights through system of equations solutions

open access: yesResults in Engineering
In this article, a systematic approach is presented for simulating turbojet engine performance at both design and off-design points. The construction of gas turbine engines involves a core, with additional components added based on the proposed ...

Turbojet engine blade damping [PDF]

open access: yes
The potentials of various sources of nonaerodynamic damping in engine blading are evaluated through a combination of advanced analysis and testing. The sources studied include material hysteresis, dry friction at shroud and root disk interfaces as well ...

On the effects of flight on jet engine exhaust noise [PDF]

open access: yes
Differences between flight data and predictions of jet engine exhaust noise were reconciled by considering the combined effects of jet mixing noise and internally generated engine exhaust noise.

Effect of afterburner lights and inlet unstarts on a mixed compression inlet turbofan engine operating at Mach 2.5 [PDF]

open access: yes
Data are presented to show the response of an uncontrolled inlet to afterburner lightoff disturbances when a mixed-compression inlet is coupled to a turbofan engine.
