WebThe aerodynamic deceleration will be accomplished by a mortar-deployed 21.5-m Viking-type disk-gap-band parachute (DGB), and will be the largest extra-terrestrial decelerator in the history of space exploration [1]. The parachute will deploy at up to Mach 2.2 and 750 Pa, resulting in the highest load and speed experienced by a parachute on Mars. WebDGB parachute are summarized in Table II. DGB fabricated, are referenced by serial number to permit variances in fab- rication to be accounted for in evaluating relative parachute performance. The data, presented for each To ensure proper decelerator performance, blockage by the vent radials was considered in determining the vent …

WebThe hemisflo DGB parachute, the triconical DGB para-chute, and the tapered DGB parachute are all the improved and optimized types based on the Viking DGB parachute. The drag coefficient of the conventional hemisflo parachute is 0.62~0.77, and the stable oscillation angle is between 10° and 15°. The hemisflo DGB parachute is a combination of WebThe supersonic parachute system is a mortar deployed 21.5 m disk-gap-band (DGB) parachute, identical in geometric scaling to the Viking era DGB parachutes of the 1970's. The MSL parachute deployment conditions are Mach 2.3 at a dynamic pressure of 750 Pa. The Viking Balloon Launched Decelerator Test (BLDT) successfully demonstrated a … ftd 2120wb

However, in case 2, suspension lines between the disk and band are omitted because they are extremely thin (please see Refs. [6,10] for their influences). Thus, the gap in case 2 is continu-ous. This is the main difference between case 1 and case 2. WebJan 29, 2024 · A 0.75m DGB parachute was tested in the NRC 2×3m wind tunnel in Ottawa. The results compared favourably with the results of the CFD/FSI analysis of the same configuration. PSP is used to determine … giggleswick sharepoint
