Abstract

The invention provides a semi-physical simulation technique device for an autonomous navigation system of an unmanned coaxial helicopter. The device consists of a helicopter-mounted navigation computer, a helicopter-mounted navigation branch box, a navigation control displayer and a navigation simulator, wherein the helicopter-mounted navigation computer is crossed and linked with the navigation simulator by the navigation branch box to form an unmanned helicopter autonomous navigation simulation loop; and the helicopter-mounted navigation computer is also crossed and linked with the navigation control displayer by the navigation branch box to realize the control and test of the helicopter-mounted navigation computer. The device creates a general development platform for the unmanned helicopter navigation system, and can test the function/performance and reliability of the navigation system under conditions of simulating actual flight; the semi-physical simulation technique which the invention relates to has good advanced property, generality and practicability; and the semi-physical simulation environment which the invention relates to has the advantages of careful design, simple structure and good operability. Practice shows that the device reduces the development period and risk of the navigation system, and has good technical and economic benefits.

Description

(1) Technical field [0001] The invention relates to a simulation technology device, in particular to a semi-physical simulation technology device for an autonomous navigation system of an unmanned coaxial helicopter, belonging to the technical field of unmanned helicopter navigation and control. (2) Background technology [0002] Semi-physical, also known as semi-physical or hardware-in-the-loop (HIL----Hardware-in-the-loop) simulation, has important engineering significance in the development of advanced unmanned aerial vehicles. Researching the corresponding simulation technology and constructing the corresponding simulation environment are indispensable material and technical means for the design and development of unmanned helicopter flight control / navigation system. [0003] Different from mathematical simulation, the main feature of hardware-in-the-loop simulation is that in the large aircraft system, some components that are the main object of simulation research are ...
