Feasibility of water injection into the turbine coolant to permit gas turbine contingency power for helicopter application [PDF]

open access: yes
A system which would allow a substantially increased output from a turboshaft engine for brief periods in emergency situations with little or no loss of turbine stress rupture life is proposed and studied analytically.

The convertible engine: A dual-mode propulsion system [PDF]

open access: yes
A variable inlet guide vane (VIGV) convertible engine that could be used to power future high-speed rotorcraft was tested on an outdoor stand. The engine ran stably and smoothly in the turbofan, turboshaft, and dual (combined fan and shaft) power modes ...

A generalized computer code for developing dynamic gas turbine engine models (DIGTEM) [PDF]

open access: yes
This paper describes DIGTEM (digital turbofan engine model), a computer program that simulates two spool, two stream (turbofan) engines. DIGTEM was developed to support the development of a real time multiprocessor based engine simulator being designed ...
