Title: Horizontal landing arrangement for a flying body
IPC: B64D17/80
Filed: 1979-10-30
Abstract: A flying body such as an aircraft or a re-entry vehicle is enabled to land substantially horizontally with the aid of one or several glider parachutes also referred to as paragliders, which are stored in an upper body zone and ejected during the landing. The lift capacity of the paraglider is so dimensioned that it replaces the lift loss of the wings due to the low landing speed, whereby the weight of the flying body is kept in equilibrium to the sum of the wing lift and of the paraglider lift. The paraglider resistance or drag is compensated by the engine thrust and an ascending or descending flight is accomplished by modulating the engine thrust.

Title: Remote power system for aircraft
IPC: F02C7/32
Filed: 1980-04-16
Abstract: In multi-shaft gas turbine engines the high pressure system is usually small relative to the low pressure system and is becoming increasingly sensitive to power off-takes in the form of bleeds for aircraft purposes or shaft power for accessory drives, particularly at altitude. The present invention modifies the aircraft auxiliary power unit or starter unit, which is in the form of a small gas turbine engine (10) for use at altitude by providing a bleed from the intermediate compressor (6) of the engine to supercharge the intake of the unit thus giving it a higher overall pressure ratio. The unit is then arranged to drive into a reduction gear (12) from which power is taken to drive an auxiliary fan (14) which is used for boundary layer control of the aircraft wing (2), or fuselage, or for blowing of aircraft flaps or augmentor wings. Alternatively power from the reduction gear is used to drive an accessory gearbox. <IMAGE>

Title: Cryogenic cooling apparatus
IPC: F25J1/00
Filed: 1980-10-10
Abstract: Cryogenic cooling apparatus of the type including a generally tubular heat exchanger affording two paths, through one of which, in use, refrigerant gas from a supply under pressure is supplied to a Joule-Thompson expansion nozzle to liquify a portion of the gas in a container where the low pressure gas returns through the other path, and a valve member co-operating with the nozzle to vary its effective area for automatically controlling the flow of the refrigerant. The valve member is actuated via an elongate operating member by a movable wall of a bellows situated within or beyond the heat exchanger and exposed on one side to the pressure of a sensing vapor, which, in operation, is in equilibrium with liquid. The operating member is in the form of a tube whose interior communicates with the space containing the sensing vapor, and extending down to the region of the nozzle so that the heat extracted from the sensing vapor in the operating member is a function of the quantity of liquid refrigerant in contact with the operating member.
