Latest Patents

Hoffman's latest patents include an integrated hydraulic control circuit for jet engine thrust reversers. This invention focuses on actuating the thrust reversers and variable exhaust nozzle on high-performance gas turbine engine powered aircraft. The hydraulic circuits for both systems are integrated into a single housing and are served by common elements. The circuit for the deployment and stowage of the thrust reverser buckets is hydraulically sequenced, inhibiting the application of hydraulic power to the actuators prior to the withdrawal of the locking pin. In a similar manner, the thrust reversers must be fully retracted before the locking pin is deployed. Additionally, the hydraulic circuit for the thrust reversers includes a pressure compensating circuit that reduces the pressure applied to thrust reverser actuators when the thrust reversers are in the stowed position.
