Integrated aircraft scale and leveling apparatus and methods for use

Abstract: A combination apparatus for weighing an aircraft has a plurality of weight scales, each scale being adapted to be supported by a support surface in a position for receiving landing gear of an aircraft thereon. At least one riser supports at least one scale above the support surface, and the height of each riser is selected to position an aircraft on the scales in a level attitude while a weight of the aircraft is being supported by the landing gear on the scales. At least one scale may be recessed in the support surface, and the height of each riser may be adjustable.

Improvements in or relating to aircraft

Abstract: 1,205,263 Ski type landing gear WESTLAND AIRCRAFT Ltd 29 Aug, 1968 [4 Sept, 1967], No 40336/68 Heading B7G An aircraft has a ski type landing gear which comprises two main skid members 10, at least two forward cantilever members 11 and an arcuate rear cross-member 13 The cantilever members are built into the skid members and pivotally attached to a fuselage at 12 The rear cross-member 13, also built in to the skid members, is attached to the fuselage at 14 and has vibration and/or recoil dampers 15 attached near the lower ends of the cross member and incorporating self-aligning ball joints at both the cross-member and fuselage attachment points Attachment lugs 16 are provided on the skid members 10 for ground handling wheels and drag struts from the aircraft to the rear cross-member may be fitted for yaw stiffness

Passive landing gear using coupled mechanical design

Abstract: The ability of UAV's (Unmanned Aerial Vehicles) to land on unknown and uneven terrain is an important area of research, particularly for applications such as field surveillance. This paper presents a novel solution to this problem using mechanical design, with a legged landing gear design that provides both suspension and stability on uneven terrain. The key features of this design are differential loading across legs as well as a conditional locking mechanism that resists post-landing disturbances. Results from a prototype design show robust stability when landing on uneven surfaces inclined up to 20 degrees, with analysis of an optimally damped suspension profile (for an approximated mass spring damper system with constant damping).

Analytical and Experimental Investigation of Base–Extension Separation Mechanism for Spacecraft Landing

Abstract: Future planetary exploration requires spacecraft to land softly on rough terrain and in severe environments. Since conventional landing methods have problems such as high rebounds and excessive resource consumption, the base–extension separation mechanism, which combines springs and separable units, is proposed as a novel landing mechanism. Although the mechanism performed good soft landings, the performance evaluation was limited. Therefore, this study evaluated its performance multilaterally. The proposed technology was analytically compared with two other landing technologies: a generalized-hybrid momentum exchange impact damper and an aluminum foam landing gear. The proposed technology suppressed rebound and acceleration better than the generalized momentum exchange impact damper. Once the components of the proposed technology had been lightened, its energy conversion efficiency matched that of the aluminum foam landing gear. In addition, experiments were conducted using small-scale models to confirm ...
