The Main parachute webbing length is WA,B. As of 1/15/2018, the total length is 474". Two different possibilities for materials are tubular nylon (1" and 5/8" width, both approximately 0.1") and 2000lb Braided braided Kevlar. The resulting weight and volume are shown in the table below:
Cross Sectional Area (in2) | Volume (in3) | Linear Mass Density (lb/ft) | Total Weight (lb) | |
|---|---|---|---|---|
| Tubular Nylon 1" | 0.1 | 47.4 | 0.0274 | 1.08 |
| Tubular Nylon 5/8" | 0.0625 | 29.6 | 0.0171 | 0.68 |
| 2000lb Braided Kevlar | 0.0154 | 7.3 | 0.00454 | 0.18 |
As described in the Webbing Materials Trade Study, we currently expect to use braided Kevlar, but have provided the tubular nylon in the table above as descope options.
Drogue Parachute Length
The Drogue parachute webbing length is the combination of WA,E,F,G (aka WE,F,G) and WC,D,F. As of 1/15/2018, the total length is 472". As described in the Webbing Materials Trade Study, we will be using 750lb braided Kevlar.
Cross Sectional Area (in2) | Volume (in3) | Linear Mass Density (lb/ft) | Total Weight (lb) | |
|---|---|---|---|---|
| 750lb Braided Kevlar | 0.00487 | 2.3 | 0.00157 | 0.062 |
Mission Package to Fin Can Length
The mission package to fin can length is WA,H. As of 1/15/2018, the total length is 295.4". As described in the Webbing Materials Trade Study, 2000lb braided Kevlar and 1/2" tubular nylon are both viable options.
Cross Sectional Area (in2) | Volume (in3) | Linear Mass Density (lb/ft) | Total Weight (lb) | |
|---|---|---|---|---|
| 2000lb Braided Kevlar | 0.00487 | 2.3 | 0.00157 | 0.062 |
