Embodiment Construction

[0042] The present invention is described in detail below in conjunction with accompanying drawing:

[0043] The invention discloses a wind-resistant laboratory for small rotorcraft, such as figure 1 As shown, it includes: the laboratory body, which is provided with an experimental area inside the laboratory body; on the first wall of the laboratory body, at a position corresponding to the experimental area, a fan unit wind surface composed of several fans is set, and the fan unit The wind surface is controlled by the frequency converter to generate a wind field with adjustable wind speed; the frequency converter cabinets are respectively placed on both sides of the wind surface of the fan unit.

[0044] There are air inlets on both sides of the first wall, and air outlets on both sides of the second wall opposite to the first wall; the opposite design of the air inlet and the air outlet can not only ensure the balance of indoor and outdoor pressure, but also Makes the indoor...

Abstract

The invention discloses a wind-resistant laboratory for a small rotary-wing aircraft and an experimental method thereof. The wind-resistant laboratory comprises a laboratory body; and an experiment area is arranged inside the laboratory body. A wind plane of a fan set formed by a plurality of fans is arranged at the position corresponding to the experiment area on a first wall body of the laboratory body; the wind plane generates a wind field with the adjustable wind speed under control by a frequency converter. An air inlet is formed in the first wall body; an air outlet is formed in a secondwall body opposite to the first wall body; and wind speed sensors are arranged at set positions at distances to the air inlet and the air outlet. The wind-resistant laboratory has the following beneficial effects: the wind-resistant performance of the small rotary-wing aircraft can be detected in an indoor environment and the influence by the external interference factor is reduced. The fan set is controlled by the frequency converter to work and the wind speed of the wind field can be adjusted; and the wind speed fluctuation is low.

Description

technical field [0001] The invention relates to the technical field of small rotorcraft performance detection, in particular to a small rotorcraft wind resistance laboratory and an experimental method. Background technique [0002] In recent years, small rotorcrafts have developed rapidly and have been practically used in many industries. Small gyroplanes fly outdoors and are easily affected by some weather conditions, or we sometimes need them to work in some bad weather conditions, such as rainy or windy weather. However, the development of detection devices for performance indicators such as wind resistance and rain resistance of small rotorcrafts is lagging behind. [0003] The wind resistance performance of small rotorcraft is one of its important indicators, and the detection of wind resistance performance of small rotorcraft generally stays in the simulation stage, which is of great significance to the research of small rotorcraft wind resistance experimental devices...
