TL;DR: In this paper, the authors proposed a bypass valve that switches pressure to the opening when internal pressure is dropped after the landing gear operating actuator 7 is stopped with working fluid pressure in the upline 45 and the down-line 46 as pilot pressure.
Abstract: PROBLEM TO BE SOLVED: To enhance the workability of manually lighting up and down a landing gear during the ground maintenance or during an emergency landing gear lowering mode by automatically operating a bypass valve in an alighting gear for aircraft. SOLUTION: An alighting gear for aircraft comprises a landing gear 21 accommodated in a fuselage, an up-line 45 to lead a pressurized working fluid to a landing gear operating actuator 7 when accommodating the landing gear 21 in the aircraft alighting gear with the landing gear 21 driven by hydraulic pressure via the landing gear operating actuator 7, a down-line 46 to lead the pressurized working fluid to the landing gear operating actuator 7 when the landing gear 21 is developed, and a first bypass valve 6 having an opening to enable the manual operation of the landing gear operating actuator 7. The first bypass valve 6 automatically switches pressure to the opening when internal pressure is dropped after the landing gear operating actuator 7 is stopped with working fluid pressure in the up-line 45 and the down-line 46 as pilot pressure.

TL;DR: In this article, a servo-motor aerodynamic load analog device for aircraft landing gear folding and unfolding is presented, which consists of a test bench, a landing gear, a jackstay actuator cylinder, a support frame, and a load following apparatus.
Abstract: The invention discloses a servo-motor aerodynamic load analog device of aircraft landing gear folding and unfolding. The device comprises: a test bench (1), a landing gear (2), a jackstay actuator cylinder (3) connected on the landing gear (2), a support frame (4), an aerodynamic load following apparatus and an aerodynamic load analog device. The aerodynamic load following apparatus controls an aerodynamic load direction in a landing gear folding and unfolding process. The aerodynamic load analog device controls a size of the aerodynamic load in the landing gear folding and unfolding process. The servo-motor aerodynamic load analog device provided in the invention has a reasonable structure. An automation degree is high and operation is convenient. The device is suitable for various kinds of folding and unfolding simulation detection of the aircraft landing gear and can provide an accurate detection result for the aircraft landing gear design and research and development.
