An aircraft landing gear 2 is disclosed having a first arm 6a configured to have one or more wheels 8a mounted at one end, the first arm 6a being configured for mounting to a pivot 10a. The landing gear 2 includes a second arm 6b configured to have one or more wheels 8b mounted at one end, the second arm 6b being configured for mounting to a pivot 10b. The landing gear 2 further includes a first link 18a pivotally coupled to the first arm 6a, a second link 18b pivotally coupled to the second arm 6b; and a main link 20 pivotally coupled to each of the first and second links 18a, 18b and to a shock absorber 22 arranged to provide a biasing force via (i) the main linkage 20 and the first link 18a which opposes rotation of the first arm 6a about the pivot 10a and (ii) the main linkage 20 and the second link 18b which opposes rotation of the second arm 6b about the pivot 10b.

MECHANICAL LINK WITH PRELOAD VERIFICATION
20210016874 · 2021-01-21 ·

A mechanical link (100) comprises a shaft (102). A first mounting interface (108) extends from the first end portion (104) of the shaft (102) and is not movable relative to the shaft (102). A second mounting interface (110) is threadably coupled with the second end portion (106) of the shaft (102). A tubular sleeve (114) circumscribes a portion of the shaft (102) and comprises a slot (116). A pin (112) extends from the shaft (102) and passes through the slot (116). A stop (124) is coupled with the second end portion (106) and fixed to the shaft (102). A washer (126) circumscribes a portion of the shaft (102) between the tubular sleeve (114) and the stop (124). A spring (122) biases the tubular sleeve (114) toward the stop (124). A first jam nut (132) is threadably coupled with the second end portion (106) between the second mounting interface (110) and the stop (124).

Pneumo-Mechanical Landing Gear Deployment System and Method

A pneumo-mechanical landing gear deployment system includes a dual-stage handle operatively connected to a pressurized tank, a nose landing gear pneumatically connected to the pressurized tank, and a main landing gear pneumatically connected to the pressurized tank. Actuation of the dual-stage handle to a first position opens the pressurized tank thereby deploying the nose landing gear. Actuation of the dual-stage handle to a second position causes further opening of the pressurized tank thereby deploying the main landing gear. The system may be employed as a backup landing gear deployment system in the case of a primary landing gear system failure.
