Abstract

The invention belongs to the field of helicopter power system design, and discloses a single-engine failure training method for a three-engine helicopter. Compared with a single-engine failure OEI training function of a current helicopter, on the premise that the flight safety is further improved, more real simulation of the real OEI flight state can be achieved. Therefore, a pilot can be trainedto handle the OEI flight state more accurately, the training function can be used for replacing a real OEI flight subject in the test flight process, the test flight evidence obtaining period is greatly shortened, the test flight evidence obtaining cost is greatly reduced, and the flight safety of risk subjects is improved. The method can be applied to three-engine helicopters, and the design logic of the method can also be applied to double-engine helicopters or multi-engine helicopters.

Description

technical field [0001] The invention belongs to the field of helicopter power system design and relates to a single-engine failure training method for a three-engine helicopter. Background technique [0002] Helicopter single-engine failure OEI state is an important failure mode that multi-engine helicopters may encounter during use, and has a great impact on the flight safety of the helicopter. When one of the engines of the multi-engine helicopter fails, the rest of the engines will be automatically upgraded to the OEI emergency power state to increase the power output of the remaining engines. This power state has strict restrictions on the use time, generally a single use is limited to 2.5 minutes, and there is a strict cumulative time limit within the entire engine overhaul interval TBO. Once exceeded, the life of the engine will be shortened and the engine will be returned to the factory for repair in advance, resulting in a large amount of economic costs. [0003] T...
