Description

Technical Field

[0001] This invention relates to, but is not limited to, the field of helicopter cockpit ergonomics, specifically to a tandem helicopter cockpit with a variable configuration. Background Technology

[0002] The design and layout of the tandem helicopter cockpit are crucial aspects of helicopter development. A well-designed cockpit can not only reduce the overall drag area of ​​the aircraft, improve flight performance, and lower the probability of being detected by the enemy, but also provide the pilot with a comfortable cockpit environment and improve cockpit ergonomics.

[0003] Existing design evaluation methods for tandem helicopter cockpits typically fall into two categories: one involves constructing a 3D model and then conducting virtual simulation analysis. This simulation analysis, based on the anthropometric data of virtual dummies in national military standards, provides evaluation conclusions but cannot meet the increasing requirements for pilot height and dimensions. The other method involves completing cockpit production and assembly, followed by pilot evaluation and verification after the helicopter's maiden flight. However, according to the development and deployment schedule, this method cannot accommodate changes to the helicopter's structural shape and cockpit intersection data after the maiden flight. Clearly, existing evaluation methods cannot provide case studies and on-flight verification of the cockpit shape and equipment layout in the early stages of helicopter design.

In this tandem helicopter cockpit, the front cockpit windshield assembly, the front cockpit instrument assembly, and the rear cockpit instrument assembly are all included. All components are adjustable in both altitude and heading directions. The rear cabin floor 21 and rear cabin windshield assembly are adjustable in altitude, while the front cabin seat 12 and rear cabin seat 19 are adjustable in both altitude and heading directions. The control consoles and joystick systems in the front and rear cabin control assemblies are also adjustable. Based on the adjustability of various components in the tandem helicopter cockpit, the tandem helicopter cockpit can be positioned in the configuration to be evaluated for evaluation by adjusting the height, fore-aft position, or roll angle of each component. The variable configuration tandem helicopter cockpit provided by this invention can be applied to verify the cockpit shape design, the intersection data design of the front / rear cabin systems, and the layout of the equipment on the instrument panel and the control panel during the tandem helicopter cockpit design phase. This reduces iteration time, improves the efficiency and accuracy of evaluation, saves development costs, and effectively solves the problem of onboard multi-scheme evaluation during the tandem helicopter design phase.
