摘要:
A system comprising an aerial vehicle or an unmanned aerial vehicle (UAV) (100,400,1000,1500) configured to control pitch, roll, and/or yaw via airfoils (141,142,1345,1346) having resiliently mounted trailing edges opposed by fuselage-house deflecting actuator horns (621,622). Embodiments include one or more rudder elements (1045,1046,1145,1146,1245,1345,1346,1445,1446,1545,1546) which may be rotatably attached and actuated by an effector member (1049,1149,1249,1349) disposed within the fuselage housing (1001) and extendible in part to engage the one or more rudder elements.
摘要:
A gurney flap arrangement comprising: an airfoil (2) with a trailing edge (6) and an opening (14) in a surface (8) of the airfoil (2); a gurney flap (1) having a first position in which at least a portion of the gurney flap (1) extends through the opening (14) and projects outwardly from the airfoil surface (8), and a second position in which the gurney flap (1) does not project from the airfoil surface (8) or projects outwardly from the airfoil surface (8) to a lesser extent; and a gurney flap actuator (3) for moving the gurney flap (1) between at least the first position and the second position. The gurney flap actuator (3) is arranged to move the gurney flap (1) in a direction that extends along an inclined angle with less than 90 degrees between the gurney flap (1) and a part of the airfoil surface (8) extending from the opening (14) toward the trailing edge (6) such that when moving from the second position into the first position a distal edge (16) of the gurney flap (1) moves both outward from the airfoil surface (8) and also in a direction extending along the airfoil surface (8) toward the trailing edge (6).

An aircraft flap 3 is equipped with: a flap body 8 which is provided so as to be deployable with respect to a main wing 2; and inclined portions 5 which are provided so as to protrude on the upper surface 301 of at least the end 40 on the outboard OTB side in the span direction D2 of the flap body 8, and are inclined to the aircraft axial direction D1; and a protruding portion 7 which protrudes smoothly from the lower surface 302 of at least the end 40 on the outboard side. The rear end 52 of each of the inclined portions 5 is located closer to the side end edge 301A of the end 40 in the span direction D2 of the flap body 8 than the virtual line VL that passes through the front end 51 of the inclined portion 5 and is parallel to the aircraft axis direction.
摘要:
A method for joining one or more first-type thermoset components (1) to a second-type thermoset component (2), each first-type thermoset component (1) being manufactured by providing an uncured starting thermoset component (11) on which a thermoplastic material layer (3) is placed, such that an interpenetrating network (21) forms between the thermoset polymer (11) of the starting thermoset component (1) and the corresponding thermoplastic material layer (3) when each first-type thermoset component (1) is cured; and each first-type thermoset component (1) being then placed on an uncured second-type thermoset component (2) so that when the latter is cured, a further interpenetrating network (22) forms between each thermoplastic material layer (3) and the thermoset polymer of the second-type thermoset component (2); this results in a strong joint between the first-type (1) and the second-type (2) thermoset components.
摘要:
A seal assembly for closing an aperture in an aerodynamic surface of a structure, the seal assembly comprising: a track for attachment to the structure; and a retractable seal including a flexible substrate and a plurality of rods connected to the substrate, wherein at least one of the rods is mounted for running movement along the track, and the seal is moveable between an extended position and a retracted position by moving the at least one rod along the track accompanied by folding/unfolding of the seal substrate, and wherein the seal is biased to its extended position.
摘要:
A flap support structure (6) for an aircraft wing (3) having a trailing edge flap (5), the flap support structure comprising: a flap support beam (10) including an aerodynamic fairing (17); and a drive unit (13) including a universal support structure (18) which rotatably receives a drive shaft (25) connected to a drive arm (14a) for moving the trailing edge flap, wherein the universal support structure also forms part of the flap support beam and supports the aerodynamic fairing.
摘要:
A high-lift device (3) comprises a flap body (11) which is provided at a rear portion of a main wing (2) which generates a lift for the air vehicle such that the flap body is deployed with respect to the main wing and stowed in the main wing and extends along a wingspan direction of the main wing (2); and a gap increasing section (20, 30) provided at an end portion (11a) of the flap body (11) in an extending direction of the flap body, to increase a gap between the rear portion of the main wing (2) and a front portion of the flap body (11) in a state in which the flap body is deployed.
摘要:
A gurney flap assembly (50) has an actuator (100), a flexible or hinged body (155), the body flexing from a retracted to a deployed position in reaction to motion of the actuator, and a first seal (162) extending along a first edge of the flexible body (155). that flexes from Linear motion of the actuator output (100) is transposed to the gurney flap (155) thereby moving it from a retracted position into the airstream. This trailing edge device will improve airfoil lift.
