Abstract

The invention provides an upright Mars aircraft single rotor system lift-drag characteristic measuring device and relates to a measuring device. The invention aims at providing the upright Mars aircraft single rotor system lift-drag characteristic measuring device to solve the problem that a traditional earth single rotor system lift-drag characteristic measuring device is hard to provide sufficient flying rotation speed to measure a lift-drag characteristic with high accuracy. The upright Mars aircraft single rotor system lift-drag characteristic measuring device comprises a rotor module, a power module and a measuring module; and the rotor module, the power module and the measuring module are fixedly connected with each other in the rotating shaft direction of a rotor system in sequencefrom top to bottom. The upright Mars aircraft single rotor system lift-drag characteristic measuring device is used for the field of aircraft single rotor system lift-drag characteristic measuring.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for lift-drag characteristics of a single-rotor system of an upright Martian aircraft. Background technique [0002] The thin atmospheric environment on the surface of Mars can provide flight conditions for low-altitude flight on Mars. However, due to the complex and changeable physical characteristics of the Martian atmospheric environment, the flight performance evaluation of Mars vehicles still needs further study. At present, the aircraft that can be used to fly on the surface of Mars mainly include rotary-wing aircraft, fixed-wing aircraft, flapping-wing aircraft, and floating air balloons. The flying height realizes hovering flight, collects the surface topography of Mars and believes it and interacts with the information of the Mars rover, assists the Mars rover to realize the path planning on the surface of Mars, and avoids high-risk areas such as craters. Due to ...
