Linear dynamic mathematical model and identification of micro turbojet engine for Turbofan Power Ratio control

open access: yesAviation, 2019
Micro turbojets can be used for propulsion of civilian and military aircraft, consequently their investigation and control is essential. Although these power plants exhibit nonlinear behaviour, their control can be based on linearized mathematical models

Unsteady flow characteristic analysis of turbine based combined cycle (TBCC) inlet mode transition

open access: yesPropulsion and Power Research, 2015
A turbine based combined cycle (TBCC) propulsion system uses a turbine-based engine to accelerate the vehicle from takeoff to the mode transition flight condition, at which point, the propulsion system performs a “mode transition” from the turbine to ...
