摘要:
The present disclosure relates to a control system for a vehicle, comprising: at least one compressor arranged to generate compressed fluid having a massflow rate; at least one fluidic control effector in fluidic communication with the at least one compressor and arranged to change the direction of travel of the vehicle when the compressed fluid is incident on the at least one fluidic control effector; a dump duct for expelling excess compressed fluid not delivered to the at least one fluidic control effector out of the vehicle; a dump valve for controlling the massflow rate of compressed fluid delivered to the dump duct; and a controller electrically coupled to the dump valve and configured to adjust the dump valve. The present disclosure also relates to an aircraft having the control system and a method of controlling a vehicle.

An air cushioned landing system for an air vehicle comprises an inflatable and deflatable skirt (113) in the form of a tube having inner (101) and outer (100) walls. The inner wall defines a central plenum (116) within the skirt, the skirt including gas pockets (130) arranged to stiffen one or more regions of at least one of the inner (101) and outer (100) walls during deflation of the skirt.
摘要:
A ducted air flow vehicle including a fuselage having a longitudinal axis, a first cockpit on one side of the longitudinal axis, a center portion adjacent and below the first cockpit, a first air flow duct mounted in the fuselage and including a first prime air mover to force surrounding air flow through the first air flow duct, and a second air flow duct mounted in the fuselage and including a second prime air mover to force surrounding air flow through the second duct, where outer upper and lower surfaces of the center portion are aerodynamically shaped to enhance production of aerodynamic lift forces by air flowing over the center portion and reduce resistance to air flow exiting the first airflow duct.
摘要:
A ground effect transport system comprising a plenum roof platform (27) for location beneath a load carrying means, a skirt (13) depending from the platform (27) to form a plenum chamber (11) with the platform (27), fan means on or in the platform for supplying air to the plenum chamber (11), wherein the skirt (13) extends downwardly towards the ground surface (43) and has a ground engaging support member (44) for supporting the bottom of the skirt (13) above the ground surface and a separate detachable sealing member (52) for providing a seal between the bottom of the skirt (13) and the ground surface (43).
摘要:
A hybrid air vehicle (100) is disclosed in which a cover is provided for a plurality of air cushioned landing pads (206) to reduce drag when airborne. The pad is inflatable to provide an air cushioned during touchdown and deflatable during flight of the air vehicle. The cover can include a first cover portion and a second cover portion. A first cover roller of the first cover portion and a matching second cover roller of the second cover portion abut to cover the corresponding pad. The first cover roller and the second cover roller, which are separate and free from a physical linkage there between, are separable in an eyelid fashion to expose the corresponding pad. A separation gap between the first cover roller and the second cover roller is increased or decreased by roller straps to cover or expose the corresponding pad.
