Helicopter and turboshaft engine mixed dimension simulation method and system, equipment and storage medium

Abstract

The invention discloses a helicopter and turboshaft engine mixed dimension simulation method and system, equipment and a storage medium, and the method fully considers the mutual influence relationship between a helicopter and a turboshaft engine, and innovatively adopts the coupling parameter between the simulation calculation of the helicopter and the turboshaft engine as a medium to carry out iterative calculation. According to the method, three-dimensional numerical simulation of the helicopter and overall performance simulation of the turboshaft engine are combined, and the two numerical simulation processes and results are associated and iterated. The final calculation result obtained by adopting the method is closer to the real working condition of the helicopter and the turboshaft engine, the collaborative research and development design efficiency of the helicopter and the turboshaft engine can be improved under the condition that the calculation process complexity and the calculation duration are not obviously improved, and the economic and time loss caused by iteration during independent design is reduced; the method can be used as one of solution ways for computer aided design of modern novel helicopters and turboshaft engines.

Description

Technical field [0001] The present invention relates to the field of numerical simulation technology, in particular, to a helicopter and turboshaft engine hybrid dimensionality simulation method and systems, equipment, storage media. Background [0002] Helicopters in the military field and civilian fields have a large number of applications, and play an increasingly important role, with the rapid improvement of computer computing power, computer numerical simulation in helicopters and as a helicopter power turboshaft engine design has been widely used. Schematic diagram of the structure of the helicopter as shown Figure 1 As shown, where 1 is the intake tract, 2 is the rotor, and 3 is the tail rotor, by Figure 1 It can be seen that the high-speed rotation of the rotor when the helicopter is working will produce a strong downward wash flow, and the suction effect of the turboshaft engine when working will lead to the suction of the rotor under the rotor through the intake tract, ...
