Abstract: An array of mirrors of the SSM ('Second Surface Mirror") type is fixed to the outer surface of a panel of a spacecraft, for example an artificial satellite, for the purpose of heat control. The fixing of the mirrors to the panel is achieved by gluing in a series of operations which ensure the correct positioning of the mirrors, the effectiveness of the adhesion, and electrical conductivity through the array of mirrors. In the application of the mirrors, use is made of a fixed structure for supporting the panel, a transferring tool on which the mirrors are temporarily retained in contact with separate support areas by a vacuum, and a loading tool arranged to receive the mirrors from the transferring tool and apply them to the panel.

Abstract: A jet propelled aircraft of the kind in which propulsion jets are directed over the top surface of the wing so as to cause additional lift as a result of the supercirculation induced on the wing and the deflection of the jets downwards, due to the Coanda effect, immediately downstream of the wing is provided with two longitudinal surfaces projecting from said top surface so as to form a single surface ejector system. The wing of the aircraft has a fixed front part which occupies a minor portion of the wing chord, and a movable rear portion which is articulated to the fixed portion about a substantially transverse axis and can be inclined downwards relative to the fixed part. The portion of the wing between the two longitudinal surfaces may be provided on its trailing edge with a movable attitude control surface of the aircraft.
