Outdoor test stand performance of a convertible engine with variable inlet guide vanes for advanced rotorcraft propulsion [PDF]

open access: yes
A variable inlet guide van (VIGV) type 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 ...

F-16 turbofan engine monitoring system

open access: yesCombustion Engines, 2019
The multirole F-16 is the most advanced aircraft in the Polish Air Forces. It has been equipped with the very modern, sophisticated and advanced turbofan engine F100-PW-229. Due to the fact, that there is only one engine, its reliability, durability, efficiency and performance are the crucial factors for the safety reasons.
