Fly-by-wire device for trainer aircraft

Abstract

The invention relates to a fly-by-wire device for a trainer aircraft, which is characterized in that: a longitudinal linkage rod, a transverse linkage rod and a course linkage rod passes through two sides of each of front and back cockpits; and a displacement sensor, an eddy-current damper and an adjustment mechanism are arranged on the front and back cockpits respectively. The device has the advantages that: 1) the mechanism linkage is realized in both the front and back cockpits operated by a longitudinal axis, a transverse axis and a course axis, so the mechanical and electrical propertiesof the front and back cockpits are completely consistent, which contributes to the improvement of training efficiency and the safe operation of the aircraft; 2) the operating rod systems of the frontand back cockpits are changed by a few driving rod systems to pass through from two sides of a control console, so the simple layout requirements of the cockpits are met; and 3) the driving displacement sensor, the eddy-current damper, the adjustment mechanism and the like are distributed in the front and back cockpits on the premise of ensuring the important operating properties of the systems, so the whole driver operation device can make a flexible and high-efficiency use of the space of the front and back cockpits in the front and back cockpits.

[0002] The mechanical linkage between the front and rear cabin cockpit and pedals is the most effective way to effectively realize aircraft piloting training. The existing fly-by-wire control devices for trainer pilots only realize the mechanical linkage of the front and rear cabins for partial direction control, and the linkage lever system It directly passes through the middle passage, occupying the middle passage of the cockpit, and is easy to be stuck by falling foreign objects, which affects the safety of the aircraft. All accessories are arranged in a centralized manner and installed in the front cabin, hinged with the cockpit, so that the overall space is larger , sometimes placing an additional weight burden on the aircraft

This type of pilot control device has the following deficiencies: 1) During pilot training, the unlinked direction of the front and rear cabin controls is generally allocated to the control authority of the front and rear cabin pilots in a certain proportion. This method is not conducive to the students on the one hand. On the other hand, when the aircraft is piloted in a single cabin, it is impossible to realize the full maneuverability of the aircraft

2) Centrally arranged accessories add difficulty to the structural design. The mechanical interface of the front cabin control rod and pedals is complicated, which increases the difficulty of the manufacturing process and requires a large continuous space. For the relatively small cockpit space of a general trainer, it is often impossible to complete layout

3) The linkage rod system is distributed in the center of the cockpit, occupying the central space of the cockpit when passing through the cockpit, and the rod system is exposed to the outside and is easily stuck by foreign objects, or adding an auxiliary floor will bring extra weight to the aircraft; rods passing outside the cockpit The tie rods pass through the cockpit, which is not conducive to the sealing of the cockpit
