An experimental device for measuring the lift of single-duct and single-duct aircraft

Abstract

The invention discloses an experimental device for measuring the lift force of a single duct and a single duct aircraft, which mainly includes a duct experiment prototype, an experimental vehicle base, guide post chute, No. 1 guide post, No. 2 guide post, and No. 3 guide post , screw piercings, fixing sleeves, tension gauges and tethering cables. It is characterized in that: the duct test prototype is a single duct type, installed on the base of the test vehicle; the base of the test vehicle is triangular, and there are guide post slide grooves on the three beams of the test vehicle base; No. 1 guide post, No. 2 guide post, The No. 3 guide pillars are respectively installed on the three guide pillar chutes of the base of the test vehicle; each guide pillar is provided with screw holes at a certain distance; the fixing sleeve is set on each guide pillar, and the screw perforation fixes the fixing sleeve; the fixing sleeve A tension measuring device is installed between the duct test prototype and the duct test prototype; the mooring cable is connected to the duct test prototype. The invention has the advantages of providing practical, safe and reliable test means, which can improve test efficiency and reduce test cost.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an experimental device for measuring the lift force of a single-duct and single-duct aircraft. Background technique [0002] In recent years, with the rapid development of vertical take-off and landing aircraft, more and more ducted power systems have been applied. However, this kind of power system lacks experience in testing lift, lacks experimental equipment, and does not have many testing methods, so the test results are not ideal. With the rapid development of ducted vertical take-off and landing aircraft today, it is more and more necessary to solve the above problems. In view of the above defects, the present invention proposes a simple, convenient and efficient method for testing the lift force of single-duct and single-duct type VTOL aircraft, which can effectively solve the above problems to a certain extent. SUMMARY OF THE INVENTION [0003] The purpose of the present inven...
