 Appl.No PCT/FR1998/000310 Applicant HISPANO-SUIZA AEROSTRUCTURES Inventor BAUDU, Pierre, André, Marcel
The invention concerns a bypass turbojet thrust reverse system comprising pivoting doors (7a, 7b) integrated in direct jet in the outer wall of the fan air duct (15) and constituting flux deviating obstacles providing thrust reversal. At least two actuators (23) controlling the door (7a, 7b) movements are associated with a synchronising device (19) consisting of an electric motor (20) and its electronic power system (21) and a bezel box (22) connected by a transmission linkage (26) to each actuator (23) respectively. Thus the security of operation is ensured in the event that the door is not locked.

The invention concerns a turbojet thrust reverser comprising a fixed upstream ring-shaped structure (11) and a downstream ring-shaped structure (12) movable in translation between an upstream position wherein an upstream part of said downstream structure (12) is housed inside the upstream structure (11) and a downstream position wherein it produces a variation in the exhaust section between the turbojet primary cowl (15) and the downstream structure (12) radially inner wall. The downstream ring-shaped structure (12) further comprises doors (20) integrated in closed position, in direct jet, in the pod wall and deviating at least part of the turbojet exhaust flow, in unfolded position providing thrust reversal after the translation of the downstream structure (12).

A jet engine thrust reverser comprising pivoting doors (20) that are integrated into the outer exhaust duct wall in the direct thrust position, and form deflecting buckets in the thrust reversal position. Said door (20) pivots about a shaft (21) located downstream therefrom, the upstream edge projects into the duct and the door (20) remains within the space occupied by the pod. The door (20) comprises an internal nozzle space (37) between a first upstream opening (36), an inner panel (27), an outer panel (29) and a second opening (32) provided on the downstream side between a downstream edge and said outer panel (29). In the thrust reversal position, at least part of the deflected flow passes through said internal space (37) of the scoop-like door (20), whereas in the direct thrust position, the second opening (32) is covered by a covering member (33) integral with the fixed structure, and the forces exerted by the flow on the inner panel (27) maintain the door (20) in the closed position.

A bypass jet engine thrust reverser comprising pivoting doors (7) integrated into the outer pod wall in the direct thrust position and pivoted out by a hydraulic cylinder (8) to form deflecting buckets for thrust reversal. An internal upstream panel (20) lines the inner surface of each door (7), and the door (7) and the upstream panel (20) are pivotable about separate respective pivots (27, 28). The door (7) and the upstream panel (20) are joined together via a so-called three-point linkage (30) hinged to a first point (31) on a support (32) secured to the upstream panel (20), to a second point (33) on the door (7), and to a third point (34) at the end of the rod of the control cylinder (8), whereby no opening torque is transmitted to the door (7) in the direct thrust position by the pressure forces exerted on the upstream panel (20).

The present invention relates to a vegetal soil mixture for cultivated turf that also comprises a rocky material, preferably marble crumbs having a fraction size between 3 and 10 mm. This mixture comprises the following components in wt.%: from 60 to 80 % of sandy or clayey soil or black earth; from 5 to 20 % of peat; from 2.5 to 10 % of rocky material; the balance being sand. The method for producing this mixture comprises sifting the sandy or clayey soil or black earth using a screen having cells not exceeding 12 mm. The mixture is then fed under dry weather conditions into a drainage system or spread onto the subsoil in a layer having a thickness between 3 and 50 cm depending on the future use of the turf. This layer is applied from the centre of the lawn towards its edges while maintaining the slope of the subsoil or drainage system. The surface of the added or flattened mixture is then rolled using a wooden compactor that weighs up to 100 kg and comprises a drum with a diameter and a length varying from 80 to 120 cm and from 130 to 150 cm respectively. The mixture thus applied is further submitted to vapour treatment for 3 to 4 weeks in order to settle and watered daily in the absence of rain.

The invention concerns a traction system for a propeller-driven transport aeroplane comprising at least a first and second pair of propellers (11, 12; 31, 32) mounted in the aeroplane wing plane. Each pair of propellers comprises two propellers symmetrically arranged on either side of the aeroplane central and longitudinal axis XX'. The first and second propeller pairs(11, 12; 31, 32) are driven independently of each other, respectively by first and second engine units (10, 30) arranged side by side in the aeroplane fuselage and by first and second independent transmission assemblies (13, 33).

A dual flow turbojet thrust reverser has pivoting doors (7) forming deflection members when operating in thrust reversing mode. Each door (7) is lined on its inner surface, in a closed position thereof, with an upstream panel (22) smoothing the fluid stream in direct jet mode. The upstream panel (22) which is not connected to the door (7) can rotate, when in thrust reversing mode, in a direction opposite to that of the door (7) so that its upstream edge is radially closer to the duct axis than its downstream edge, thus forming a scoop that picks up an inner portion of the stream to control the reverse flow layers and to provide for efficient thrust reversal.

 Appl.No PCT/FR1998/001482 Applicant HISPANO-SUIZA AEROSTRUCTURES Inventor BAUDU, Pierre, André, Marcel
The invention concerns an aircraft turbojet thrust reverser specially designed to resist shocks from objects coming from the turbo-shaft engines around which they are arranged, such as wrecks of vanes or disks, said shocks being capable of deforming the thrust reverser ring-shaped structure or break the stiffeners thereof. Said reverser is characterised in that the emergency locking systems (33) comprise each an articulated slide bolt (38) one end of which has the shape of a hook (40) partially enclosing the locking interface (43), the slide bolt (38) being automatically returned for closing by elastic means (47). Such arrangement enables to produce additional mechanical links capable of compensating deformations of the thrust reverser ring-shaped structure or the breakage of stiffeners.
