For example, the fixed part is located in the upper part of the cowling, the mobile part being located in the lower part of the cowling. | 11-13-2008 |
20090025366 | PROPULSION UNIT FOR AIRCRAFT AND AIRCRAFT COMPRISING AT LEAST ONE SUCH PROPULSION UNIT - An aircraft propulsion unit including a turbojet and a heat exchanger located above the turbojet and drawing a cooling air stream and a hot air stream in the turbojet. Wherein the cooling air intake and hot air intake surfaces in the housing are directed forward of the turbojet and have normal lines inclined relative to the axis of the turbojet. The embodiment also concerns an aircraft equipped with at least one such propulsion unit. | 01-29-2009 |
20090121078 | AIRCRAFT POD AND AIRCRAFT EQUIPPED WITH AT LEAST ONE SUCH POD - A pod for an aircraft including a cowling, an engine housed in the inner volume of the cowling, an annular channel circulating a secondary thrust flow arranged between the engine and the cowling, and at least one thrust reverser for forming a reverse flow from the secondary thrust flow circulating in the annular channel. The thrust reverser including a plurality of doors provided in the rear part of the cowling, so as to form a trailing edge of the cowling. The thrust reverser can include means for actuating the doors such that at lease one actuating means actuates two adjacent doors and at least one door is actuated by two actuating means. | 05-14-2009 |
20090218441 | Device for Fastening A Turbojet Engine to an Aircraft Fixing Strut - A front attachment device for fastening a turbojet engine to an aircraft fixing strut. The attachment device is adapted to absorb the turbojet engine thrust loads, and includes a top bracket, and a lower bracket. A thrust load absorption vector results from a first convergence point of primary vectors passing through primary fixing points that couple the top bracket to the lower bracket and a second convergence point of secondary vectors passing through secondary fixing points that couple the lower bracket to the turbojet engine. The thrust load absorption vector transmits the turbojet engine thrust loads to the fixing strut, and extends along a longitudinal axis of the turbojet engine. | 09-03-2009 |
20090301101 | Heat exchanger, propulsion unit and aircraft provided therewith - A heat exchanger provided with a heat exchanger housing for circulating a cooling air flow and a hot air flow therein including a hot air input channel placed on the housing rear side for supplying the hot air flow to the heat exchanger housing and a cooling air discharge channel arranged on the rear side of said heat exchanger housing for exhausting the cooling air flow therefrom, wherein the channels are concentrically shaped. The disclosed embodiments also relate to a propulsion unit provided with the inventive heat exchanger, wherein the cooling air discharge channel arranged in the rear part of the housing crosses the strut in such a way that the cooling air flow is exhausted behind a jet engine. An aircraft provided with at least one inventive propulsion unit is also disclosed. | 12-10-2009 |
20100237200 | Turbojet engine for aircraft, propulsion unit comprising such a turbojet engine and aircraft comprising such a propulsion unit - A propulsion unit comprises a turbojet engine and a thermal exchanger, situated above the turbojet engine. The turbojet engine comprises a regulation device to regulate an air flow-rate in a cooling air lead-in conduit conveying a stream of cooling air into a thermal exchanger, The regulation device regulates the air flow-rate upstream with respect to the cooling air lead-in conduit | 09-23-2010 |
