Abstract

The invention discloses a device and a method for detecting the velocity of the incoming flow of a propeller. The detection device includes: a load characteristic measuring device and a data processing device; the load measuring device is respectively connected with the data processing device and the target propeller; the target propeller includes: a propeller of a cross-medium aircraft; the load characteristic measuring device is used for: measuring the load of the target propeller Parameter characteristics; the data processing device is used to: match the load parameter characteristics of the target propeller with the load parameter characteristics of similar propellers in different medium environments, so as to determine the medium environment in which the target propeller is located, and obtain the target medium environment; The simulated incoming flow velocity data in the medium environment is used to calculate the incoming flow velocity corresponding to the target propeller in the target medium environment. The invention is suitable for various medium environments, and meets the requirement of the trans-medium aircraft for flow velocity measurement in different medium environment types.

Description

technical field [0001] The invention relates to the field of propeller detection, in particular to a device and method for detecting the incoming flow speed of a propeller. Background technique [0002] A cross-medium aircraft can fly in the air, and can also navigate on the water surface or underwater, which requires the power system to be able to operate in different media. In order to meet the requirements of high-precision control and aircraft status monitoring, the aircraft needs to independently judge the type of medium and measure the flow velocity in different medium environments. The incoming flow velocity is detected. Contents of the invention [0003] Based on this, it is necessary to provide a propeller incoming flow speed detection device and method, which are suitable for various medium environments and meet the needs of cross-medium aircraft for flow velocity measurement in different medium environments. [0004] To achieve the above object, the present in...
