WebJul 2, 2024 · According to the simulation results of the aerodynamic characteristics and heat flux density of the deployable heat-resistant spacecraft, the wind tunnel ablation test of the flexible heat-resistant material was carried out. The wind tunnel test conditions are shown in Table 3. Case I is the low heat flux ablation test condition, which mainly ... WebFeb 16, 2024 · Fw = 0.5 * v² * ρ * Cd * A. For example, a vehicle traveling at 90 kph (25 m/s) with a Cd of 0.35 and a frontal area of 2.2 m² requires a force of 288.75 N to overcome wind resistance; at 120 kph that force increases to 513.33 N, or nearly double! The last drag force is from a change in elevation, which is the only one which can actually ...
