摘要:
The present invention provides a method of manufacturing a shell component for an aircraft or spacecraft. The method comprises a step of positioning a skin panel (102), which includes a skin (104) of the aircraft or spacecraft and first and second stringers (111,112) stiffening the skin, opposite a frame (106) having first and second mouseholes (121,122) for receiving the first and second stringers, a step of elastically bending the skin panelm (102), a step of inserting the first stringer (111) into the first mousehole (121), and a step of releasing the elastic bend to insert the second stringer (112) into the second mousehole (122). Under a further aspect, the invention provides an apparatus (200) for manufacturing a shell component for an aircraft or spacecraft, comprising a positioning unit (203) for positioning a skin panel (102), whic h includes a skin (104) of the aircraft or spacecraft and first and second stringers (111,112) stiffening the skin, opposite a frame (106) having first and second mouseholes (121,122) for receiving the first and second stringers (111,112), a bending unit (204) for elastically bending the skin panel (102), an inserting unit (202) for inserting the first stringer (111) into the first mousehole (121), and a control unit (208), which controls the bending unit (204) to release the elastic bend in order to insert the second stringer (112) into the second mousehole (122).

A method of simultaneously applying three different diffusion aluminide coatings to a metal part with an external surface and internal passageways includes first placing the part in an enclosed retort. Areas of the part are then coated with aluminum containing slurry for a first diffusion aluminide coating. Interior walls of the retort are then coated with a vapor source slurry for a second vapor phase aluminide coating on the surface of the part. Areas on the surface of the part not requiring coating are coated with masking materials. A closed chamber inside the retort containing source material for a third vapor phase diffusion aluminide coating for the internal passageways is then attached to the internal passageways. The retort is then placed in a furnace under a protective atmosphere and subjected to a diffusion heat treat to coat the external surfaces and internal passageways with the three different aluminide coatings.

A launch system comprises a nose section comprising a nose coupling surface, a tail section comprising a tail coupling surface facing the nose coupling surface and a mast coupling the nose and tail sections. The mast is configured to expand and retract to displace the nose and tail sections within a range of distances from one another. In a retracted state, the nose and tail sections are either structurally coupled to one another at the nose and tail coupling surfaces or structurally coupled to at least one integrated module located between the nose and the tail sections.

The invention relates to a panel structure (1) for a vehicle, and especially for an aircraft (A) or spacecraft, comprising: an area member (2), especially a skin member, that defines an areal expanse with a first surface (3) and an opposite second surface (4) and having a thickness (5) between the first and second surfaces (3, 4); and a plurality of elongate stiffener members (6) which are attached to the area member (2) and extend over at least one of the first and second surfaces (3, 4); wherein at least one of the stiffener members (6) is bifurcated at a bifurcation point (P) into two or more branch stiffener members (6'). The invention also provides a method of producing such a panel structure (1).

The present invention pertains to a fibre reinforced plastic profile, in particular for an aircraft or spacecraft, comprising a stacked ply assembly including a plurality of stacked plies each comprising fibre material, the ply assembly having a profile cross section comprising at least one first section, at least one second section, and at least one splice section located between the at least one first section and the at least one second section. The splice section includes a first plurality of stacked plies having fibres of a first fibre material and a second plurality of stacked plies having fibres of a second fibre material. In the splice section, respective plies of the first plurality of stacked plies are intertwiningly abutted with respective plies of the second plurality of stacked plies.
摘要:
A high energy, e.g. ultraviolet (UV) catalyzed decomposing foam (124) encapsulating kinetic media (122) forms a payload (120) to be boosted in space and provides an ultra-light weight means for intercepting an incoming missile or other target (140, 142). The decomposed foam releases the kinetic media (at designed rates so as to preserve a required density of media on target) to intercept the target and destroy it. The use of the decomposing foam significantly lowers the weight and cost an improves the probability of success of destroying the target.
