Abstract

The invention discloses an experimental device for measuring a single duct and lift force of a single ducted air vehicle. The experimental device mainly comprises a ducted experimental prototype, an experimental vehicle base, guide pillar slide grooves, a first guide pillar, a second guide pillar, a third guide pillar, screw through holes, fixing sleeves, tensile force measurers and a mooring cable. The experimental device is characterized in that the ducted experimental prototype is of a single duct type and installed on the experimental vehicle base; the experimental vehicle base is in a triangular shape, and the guide pillar slide grooves are formed in three beams of the experimental vehicle base; the first guide pillar, the second guide pillar and the third guide pillar are installed on the three guide pillar slide grooves of the experimental vehicle base correspondingly; the screw through holes are formed in all the guide pillars at certain intervals; all the guide pillars are sleeved with the fixing sleeves, and the screw through holes fix the fixing sleeves; tensile force measurers are installed between the fixing sleeves and the ducted experimental prototype; and the mooring cable is connected to the ducted experimental prototype. The experimental device for measuring the single duct and lift force of the single ducted air vehicle has the advantages that practicable, a safe and reliable experimental means is provided, experimental measuring efficiency can be improved, and experimental measuring cost is reduced.

Description

technical field [0001] The invention relates to the field of aviation, in particular to an experimental device for measuring the lift of a single duct and a single duct aircraft. Background technique [0002] In recent years, with the rapid development of vertical take-off and landing aircraft, ducted power systems have been applied more and more. However, this type of power system has insufficient experience in testing lift, lack of experimental equipment, and few test methods, and the test results are not ideal. Today, with the rapid development of ducted vertical take-off and landing aircraft, 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 of single-duct and single-duct VTOL aircraft, which can effectively solve the above problems to a certain extent. Contents of the invention [0003] The purpose of the present invention is to design...
