Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the drawings:

[0024] Such as Figure 1 to Figure 4 As shown, a pedal force sensor for an airplane includes a pedal force sensor body 1 connected to a pedal pedal and a pedal control lever. One end of the pedal force sensor body 1 is rotatably connected with the pedal, and the other end is connected to the foot The pedal lever is connected by rotation; the pedal force sensor body 1 has a web structure in the middle, and there are multiple resistance strain gauges 9 attached to the web structure. Every two resistance strain gauges 9 form two Wheatstone bridges, which are composed of resistors. The Wheatstone bridge composed of strain gauges is connected with an electrical connector 6;

[0025] The pedal force sensor body 1 has a cross web structure in the middle; two resistance strain gauges are attached to the cross web structure of the pedal force sensor body 1;

[0026] Each piece of resis...

Abstract

The invention discloses a stepping force sensor for an airplane. The stepping force sensor comprises a stepping force sensor body connected to a stepping pedal and a stepping joystick system. The middle of the stepping force sensor body is of a radial plate structure, resistance strain gauges are pasted on the outer surface of the stepping force sensor body, two paths of Wheatstone bridges are formed by every two resistance strain gauges, and the Wheatstone bridges formed by the resistance strain gauges are connected with electric connectors. The stepping force sensor body is connected to thestepping pedal and the stepping joystick system, and by means of deformation generated by the stepping force sensor body in the force transmission process, control force applied to the stepping pedalby an airplane driver in the airplane driving process can be directly measured through the Wheatstone bridges formed by the resistance strain gauges. the maneuverability and flexibility of the airplane are improved, meanwhile potential safety hazards generated when the airplane flies are reduced, the safety guarantee capacity of the airplane in the flight process is improved, the measuring precision is high, the structure is simple, the design is reasonable, and the stepping force sensor can be suitable for various airborne early warning aircrafts.

Description

Technical field [0001] The invention belongs to the aviation field, and particularly relates to a pedal force sensor for an airplane. Background technique [0002] The existing pedal control force measurement methods all adopt indirect methods to measure the pedal control force exerted on the pedal control lever system by the pilot of the aircraft during the process of flying the aircraft. At present, the direct measurement of the pedal control force exerted on the pedal control lever system by the pilot of the aircraft is a major technical problem that plagues the entire aviation field. So far, it has not been able to directly measure the pilot’s driving force. The method of pedal control force applied to the pedal control lever system during the airplane. [0003] Nowadays, the international situation is changing. In addition to the traditional army operations, the air force has received more attention from various countries. The air force has higher requirements for combat mane...
