Abstract
Official abstract text for this publication.
The present invention relates to a mechanical system that modulates airflow in an aircraft inlet diffuser that is used in conjunction with an aircraft engine that integrates both a center turbine engine and a high Mach engine such as a constant volume combustor (CVC) arrangement or ramjet arrangement with intakes formed co-centrically about the turbine. The modulation system uses an articulating cone. When in a retracted position the articulating cone allows the aircraft to operate in low speed mode as only the turbo jet receives airflow. At its widest expanse, the articulating cone completely covers the turbo jet circular intake face, precluding operation of the turbine engine.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for regulating the air flow into a turbine engine, the turbine engine defining a generally cylindrical turbine face, a forward outer perimeter of the turbine face and a stationary center shaft extending forward of the turbine face, the center shaft defining an apex at a forward end thereof, the system comprising: an air flow deflector positioned upstream of the generally circular turbine face of the turbine engine, the air flow deflector being radia…
