Apparatus is disclosed for advantageously developing longitudinal, lateral, and directional attitude control and also lift control in improved manners in aircraft systems of the type capable of vertical, hovering, transitional, and conventional modes of flight operation. The aircraft system, having both a principal power plant which produces high-energy primary flow fluid and a fuselage which has attached, fixed aerodynamic liftproducing airfoils, is provided with fluid-reaction liftproducing ejector assemblies in the airfoils at locations symmetrically positioned relative to and laterally distant from the aircraft longitudinal axis and alternatively additionally at a location or locations laterally distant from such longitudinal axis and longitudinally distant from the system center of gravity. Each included airfoil lift ejector assembly is comprised of an airfoil-shaped after injector flap member, a forward ejector flap member which is spaced apart from but operated in combination with the after injector flap member in modes of flight operation other than conventional flight, a core injector essentially centered between the injector flap members, and a conduit conducting high-energy primary flow fluid from the principal power plant to a nozzle in the core injector and to Coanda-blowing slot devices in each system injector flap member during non-conventional modes of system flight. A pilot-operated control device is provided in the system for varying the divergence angles of the lift ejector diffuser sections defined by the flap members in each ejector by coordinated actuation and rotation to thereby vary the system longitudinal, lateral, and directional attitudes and also the system lift control selectively during vertical, hovering and transitional flight while perferably operating the principal power plant at substantially constant power.

A flying control system in a VTOL or V/STOL aircraft comprises a mechanical analoque ''model'' of the lift and propulsion plant of the aircraft. Vertically-disposed electromechanical transducers represent, respectively, the lift engines of the aircraft, each transducer being vertically extendible and also tiltable in the fore-and-aft direction and delivering two electrical output signals, indicating vertical extension and tilt respectively, to control respectively the throttle opening and thrust deflection of the respective engine. The transducers are actuated by a mechanical assembly that receives pilots'' command and autostabiliser inputs and is caused to ''''yaw'''', ''''roll'''' and ''''pitch'''' by movement of the rudder pedals and control column, and to translate vertically and horizontally fore-and-aft by movements of a lift control lever.

998,417. Valves. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION MOTORS D'AVIATION. April 4, 1962 [April 7, 1961], No. 13012/62. Heading F2V. [Also in Division B7] Means for distributing fluid between a plurality of receiving apparatuses, such as altitude control nozzles on an aircraft, comprises a plurality of pipes in parallel between a valve and each apparatus, the valve comprising ganged obturators so that in one valve position, flow is divided equally between the apparatuses, in another position flow is to one apparatus only, and in intermediate positions flow is apportioned between the apparatuses, at least one obturator providing an unobstructed flow passage. In Fig. 1, a valve body 1a contains a part cylindrical member with parts 6, 7, of cross-sections which are unequal arcs as seen in Fig. 2. These parts are secured to an endplate 9 rotatable by a servomotor 11 to control the admission of pressure fluid, received through duct 1, to ducts 2, 3 leading to one apparatus and ducts 4, 5, leading to another. In all positions, the fluid consumption is constant. Fig. 5 shows cross-section of a valve in which two parts 6 and two parts 7, all of differing angular extents, control admission to ducts 2, 3, 21, 31, leading to one set of jet reaction nozzles, and to ducts 4, 5, 41, 51, leading to another set. |
