Latest Patents

Medawar holds a patent for a "Thrust Spoiling Apparatus and Method." This invention features a streamline shroud that surrounds a jet aircraft engine, terminating forwardly of the aft end of the engine tailpipe, which comprises a secondary nozzle. The design includes two or more deflector doors that, when in a stowed position, form a sleeve around the aft portion of the tailpipe. The trailing edges of these doors extend downstream and converge beyond the tailpipe to create a primary nozzle. This primary nozzle has an exit flow area smaller than that of the secondary nozzle, ensuring the required mass flow, velocity, and pressure for normal flight operations. The doors can swing outwardly and rearwardly to a deployed position, effectively deflecting flow laterally and nullifying thrust. The blocking action of the deployed doors produces a back pressure effect that tends to reduce mass flow. However, the greater exit area of the secondary nozzle compensates for this back pressure, maintaining a substantially uniform mass flow.
