Description

Technical Field

[0001] The present invention relates to the field of, but is not limited to, human-machine ergonomics technology in a helicopter cockpit, and in particular to a tandem helicopter cockpit with a variable configuration. Background Art

[0002] The appearance design and cockpit layout of a tandem helicopter cockpit are very important aspects in the development process of a helicopter model. A good cockpit design can not only reduce the drag area of ​​the entire aircraft, improve flight performance, and reduce the probability of being discovered by the enemy, but also provide the pilot with a comfortable cabin environment and improve cockpit ergonomics.

[0003] There are usually two ways to evaluate the design of the existing tandem helicopter cockpit: one is to build a three-dimensional model and then conduct virtual simulation analysis. The simulation analysis gives an evaluation conclusion based on the human body size data of the virtual dummy in the national military standard, but it cannot meet the increasing requirements for the height size data of pilots; the other is to complete the cockpit production and assembly, and then conduct an evaluation and verification by the pilot after the helicopter's first flight, and give an evaluation opinion. According to the development and installation progress, the requirements for changes to the helicopter's structural shape and cockpit intersection data cannot be met after the first flight. Obviously, the existing evaluation methods cannot conduct instance evaluation and on-board verification of the cockpit shape and cockpit equipment layout in the early stage of helicopter design.
