Abstract: According to the invention, the rear part of the connecting element (1), which part is intended to be connected to a body (4) made of composite material, comprises at least one abutment (13) of annular shape, centered with respect to a longitudinal axis (10) and intended to come into contact with the front edge (14) of said body (4), and a longitudinal rearward extension (15) which is defined from said abutment (13) onward and which comprises a contact face (16) and has a shape and diameter suited to said body (4) so that its contact face (16) can come laterally into contact with a peripheral surface (17) thereof.

Abstract: A flying object includes a lift and displacement motor which has a combustible propelling charge and direct thrust flight control and can ensure the lift and displacement of the flying object in an observation position for which the flying object is at least approximately vertical with the rear part thereof oriented downwards; an attitude motor with a combustible propelling charge and conventional thrust vector control; and an observation unit which is arranged in the rear part of the flying object.

Abstract: The invention relates to a flying object (1) comprising a lift and displacement motor (3) which has a combustible propelling charge and direct thrust flight control and can ensure the lift and displacements of said object (1) in an observation position for which the object is at least approximately vertical with the rear part (2R) thereof oriented downwards; an attitude motor (5) with a combustible propelling charge and conventional thrust vector control; and observation means (14) which are arranged in the rear part (2R).

Abstract: Shape memory alloy spring washers passing from a flat shape to a truncated cone shape on exceeding a given critical temperature (Tc) can be stacked in opposition or in the same sense with identical and/or different washers, in order to bring about a development in stages of the pressure (P) applied by the stack of washers when the temperature (T) varies. These washers can advantageously be used for the bonding and polymerization of composite material parts (C), because they make it possible to simultaneously treat several parts in the same ventilated oven and in a less expensive manner.
