Abstract: According to an aspect, there is provided a superconductor connector assembly for electrically connecting a first superconductor cable and a second superconductor cable, the superconductor connector assembly comprising: at least one first superconducting cable terminal, the first superconducting cable terminal comprising at least one first opening for receiving an end of the first superconductor cable; at least one second superconducting cable terminal, the second superconducting cable terminal comprising at least one second opening for receiving an end of the second superconductor cable; and a surrounding part that is configured to receive and surround the first superconducting cable terminal and the second superconducting cable terminal, wherein the first and second openings overlap when the first superconducting cable terminal and the second superconducting cable terminal are received in the surrounding part, wherein the surrounding part is made from a material that has a thermal expansion coefficient diff

Abstract: The present invention provides a pumped helium circuit comprising a compressor (14) with a high pressure port (16) and a low pressure port (18) each connected to a supplied equipment (61,63,65,67) to respectively supply compressed helium to, and receive compressed helium from, the supplied equipment; a pressure relief valve (12) operable to link the high pressure port to the low pressure port in response to a predetermined pressure differential; a non-return valve (13) located between a low pressure side of the pressure relief valve and the supplied equipment; and means for preventing oil carry-over from the compressor to the supplied equipment.

Abstract: Apparatus for stabilizing a weapon launched from an aircraft. The weapon is rovided with a plurality of concentric rings mounted on the nose of the weapon for reducing nose lift. The tail of the weapon is provided with a plurality of wedge shaped fins positioned on a decreasing tail diameter which increases the tail stability while minimizing tail lift. The outer faces of the fins are of a multi-tiered construction with angled portions connecting the tiers.

Abstract: A turbulence generator is provided on the forward end of a free flight ornce device to induce a turbulent boundary layer over the surface of the device. The turbulent layer generated is thicker than the normal boundary layer and helps reduce drag disparity between similar ordnance devices.

Abstract: An air launched weapon having wrap-around fins wherein the fins are provi with fences, slots and roll tabs to stabilize the roll-rate at all angles of attack.

Abstract: An apparatus and method for reducing the launch disturbance of a weapon se on a supersonic aircraft is disclosed. The apparatus comprises a flywheel rotatably mounted within the store. The flywheel is pre-spun before launch using internal rockets or ram air. The spining flywheel produces a gyroscopic effect which appreciably reduces launch disturbance and therefore increases accuracy.
