To acquire the aerodynamic characteristics of a parachute for a specific reentry capsule, a supporting device has been developed relying on the FL-62 wind tunnel. This test apparatus is designed to withstand maximum test loads up to Ma 1.6 and features an automated capability to adjust the angle of attack (AoA) within a range of 0°–15°.In the resistance characteristic tests, it is required to conduct selection trials to determine optimal parachute drag ratio. The support device can adjust the position of the leading parachute lines to ensure the parachute body remains at the same location throughout the test section. For the aerodynamic properties, the support apparatus should also be capable of real-time adjustment of the parachute's angle of attack to acquire the corresponding aerodynamic data. The results show that the supporting device achieves a repeatable positioning accuracy of less than 3’, and its stiffness and strength satisfy the requirements for parachute wind tunnel testing, the support device fulfills its design specifications.

摘要

To acquire the aerodynamic characteristics of a parachute for a specific reentry capsule, a supporting device has been developed relying on the FL-62 wind tunnel. This test apparatus is designed to withstand maximum test loads up to Ma 1.6 and features an automated capability to adjust the angle of attack (AoA) within a range of 0°–15°.In the resistance characteristic tests, it is required to conduct selection trials to determine optimal parachute drag ratio. The support device can adjust the position of the leading parachute lines to ensure the parachute body remains at the same location throughout the test section. For the aerodynamic properties, the support apparatus should also be capable of real-time adjustment of the parachute's angle of attack to acquire the corresponding aerodynamic data. The results show that the supporting device achieves a repeatable positioning accuracy of less than 3’, and its stiffness and strength satisfy the requirements for parachute wind tunnel testing, the support device fulfills its design specifications.
