TL;DR: In this paper, the main and auxiliary bays are aligned outboard of the main bay, and the landing gear can be aligned with the auxiliary bay without increasing the length or width of the aircraft.
Abstract: A fighter aircraft achieves low aerodynamic drag and radar signature without sacrificing flight performance through a unique arrangement of the main weapons bay, the auxiliary weapons bays, and the main landing gear. Separate main and auxiliary weapons bays permit a narrower fuselage than could be obtained with a single common bay. Also, the auxiliary weapons bays and the landing gear can be aligned outboard of the main weapons bay without needing to increase the length or width of the aircraft. The air intake ducts extend aft from the intake and curve upwardly and inwardly over the main weapons bay. The result of the design configuration is an aircraft which has a forward aspect reduced to the minimum necessary to accommodate the components that need forward visibilities, which translates to minimum aerodynamic drag and radar signature.

TL;DR: In this article, a device and a method to cause the rotation of at least one wheel of the landing gear of an aircraft is described, according to which between the supporting structure (12, 12, 14, 15, 16) and the brake group (19, 20, 21, 22) of the wheel is placed at least an actuator element with variable geometry.
Abstract: The invention concerns a device and a method to cause the rotation of at least one wheel of the landing gear of aircraft, according to which between the supporting structure (12) of the landing gear and the brake group (19, 20) of the wheel is placed at least an actuator element with variable geometry (35, 38, 40, 42) controlled and managed to develop such a force in order impose an intermittent angular rotation of the wheel when the brake group is operated.

TL;DR: An auxiliary landing gear for an aircraft including a pair of auxiliary wheels mounted from the wings and including an exterior rim composed of segments connected to a hub by expansible members is described in this paper.
Abstract: An auxiliary landing gear for an aircraft including a pair of auxiliary wheels mounted from the wings and including an exterior rim composed of segments connected to a hub by expansible members whereby expansion from a collapsed inoperative disposition to an expanded operative disposition to facilitate landing on rough terrain is achieved.

TL;DR: The Langley Research Center has recently upgraded the landing loads track (LLT) to improve the capability of low-cost testing of conventional and advanced landing gear systems as discussed by the authors, and the unique feature of the Langley Aircraft Landing Dynamics Facility (ALDF) is the ability to test aircraft landing gear system on actual runway surfaces at operational ground speeds and loading conditions.
Abstract: The Langley Research Center has recently upgraded the Landing Loads Track (LLT) to improve the capability of low-cost testing of conventional and advanced landing gear systems. The unique feature of the Langley Aircraft Landing Dynamics Facility (ALDF) is the ability to test aircraft landing gear systems on actual runway surfaces at operational ground speeds and loading conditions. A historical overview of the original LLT is given, followed by a detailed description of the new ALDF systems and operational capabilities.
