The temperature in the front region of a hypersonic vehicle nose can be extremely high, for example, reaching approximately 11 000 K at a Mach number of 36 (Apollo reentry) due to the bow shock wave. In this case, accurate prediction of temperature b

The temperature in the nose region of a hypersonic vehicle can be extremely high, for example, reaching approximately 11 000 K at a Mach number of 36 (Apollo reentry). The bow shock wave is normal, or nearly normal, in the nose region of a blunt body

The range of unmanned aerial aircraft (UAV) is developing continuously generating new constructive solutions from small size and mass to those, which are comparable to piloted aircraft. The main reason of UAV use is due to lower cost of design, reali

Dynamic stability of reentry capsules, in the low supersonic regime, has a major impact in the phases prior to the parachute deployment. Capsule’s velocity and orientation affects strongly the sizing and deployment of the parachute and dictates the
