註釋

The current parachute-canopy design methodology is mainly empirical. Under certain conditions, parachutes have been observed to collapse during periods of rapid deceleration, subsequent to the initial inflation of the canopy with a resulting loss of drag and ultimately the payload. Studies began with a two-dimensional model of flow about a rigid, nonporous camber. Even though highly idealized, the purpose of the investigation was not a solution of an immediate practical problem but to understand the physics of the problem. (JES).
