Abstract
Official abstract text for this publication.
Vehicles, such as aircraft, may include turbine-based combined cycle power plants (TBCC) for power to achieve high-mach speeds. An anti-unstart configuration provides control for transitioning between the amount of air directed to either engine during operation of gas turbine engine and scramjet engines, to avoid unstart during operation above sonic speeds.
First claim
Opening claim text (preview).
What is claimed is: 1. A turbine-based combined cycle (TBCC) propulsion system for an aerospace vehicle, the system comprising a flow passageway including a common inlet section for receiving air from the environment, a pair of propulsion segments each connected with the common inlet section, and a common exhaust section connected with each of the propulsion segments for discharging exhaust products, wherein the common inlet section includes an apportionment control flap for guidi…
