Extensive parafoil wind tunnel tests were carried out. Parafoil model sizes ranged from .09 sq ft to 147 sq ft and parafoil aspect ratios ranged from .5 to 3.0. The wind tunnel test velocities ranged from approximately 20 ft per second to over 60 ft per second. The aerodynamic stability co...
NASA has developed and tested a large parafoil for use in landing the International Space Station crew return vehicle. A series of tests using low-velocity airdrop pallets and prototype lifting bodies flights has demonstrated that the parafoil recovery system is a viable option for safely landing ...
Flight tests and wind tunnel experiments are difficult to analyze the aerodynamics of parafoil because of the limitation and difficulty of data measurement in an unknown environment. The objective of this study was to computationally derive the aerodynamic characteristics of parafoil, as an alternative ...
The four main processes of flight tests are shown in Figure 2. The UAV system first carries the parafoil to the target altitude, and when it reaches the target altitude, the UAV releases it in the air. The whole flight process of the parafoil is controlled by the remote control device. ...
