  • Method for controlling a twin-clutch transmission
    Patent number: 7409885
    Abstract: The invention concerns a method of controlling a twin-clutch transmission (10). When the torque transmitted in a first transmission path (C1, E2, Z8, Z9, S2, Z3, Z4) reaches an upper limit given by the torque transmission capacity of that path further additional torque produced by an engine at the drive shaft (I) is transmitted by closure of the second clutch (C2) to the output shaft (O) in parallel relationship by way of a second transmission path (C2, E1, Z1, Z2, S1, Z3, Z4). That permits the output of the engine to be better utilised and makes it possible to achieve better travel characteristics.

  • SYSTEMS AND METHODS FOR TILTER MOTOR COOLING
    Publication number: 20240190566
    Abstract: A VTOL aircraft includes a plurality of tilt propellers configured to be rotated between a forward cruise configuration and a vertical lift configuration. A nacelle or other structure may be configured to form a low pressure zone from the wake of the tilt propellers when operating in the lift configuration. The low pressure zone may include an outlet side of a cooling path. Due to the low pressure, airflow may be induced through the cooling path even in the absence of strong air pressure at the inlet side. During a cruise operation when the VTOL aircraft is in forward motion, the nacelle or other structure may be aligned with a baffle to form an exhaust channel for the cooling airflow.
