  2. Atmospheric entry - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_entry

    Practical development of reentry systems began as the range, and reentry velocity of ballistic missiles increased. For early short-range missiles, like the V-2, stabilization and aerodynamic stress were important issues (many V-2s broke apart during reentry), but heating was not a serious problem.

  3. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    The ballistic coefficient of an atmospheric reentry vehicle has a significant effect on its behavior. A very high ballistic coefficient vehicle would lose velocity very slowly and would impact the Earth's surface at higher speeds. In contrast, a low ballistic coefficient vehicle would reach subsonic speeds before reaching the ground. [75]

  4. Non-ballistic atmospheric entry - Wikipedia

    en.wikipedia.org/wiki/Non-ballistic_atmospheric...

    The primary goal was to have the RV change its path during reentry so that anti-ballistic missiles (ABMs) would not be able to track their movements rapidly enough for a successful interception. The first known example was the Alpha Draco tests of 1959, followed by the Boost Glide Reentry Vehicle (BGRV) test series, ASSET [16] and PRIME. [17]

  5. Planar reentry equations - Wikipedia

    where the quantities in these equations are: is the velocity > is the flight path angle is the altitude; is the atmospheric density; is the ballistic coefficient; is the gravitational acceleration

  6. Aerodynamic heating - Wikipedia

    en.wikipedia.org/wiki/Aerodynamic_heating

    Aerodynamic heating is the heating of a solid body produced by its high-speed passage through air. In science and engineering, an understanding of aerodynamic heating is necessary for predicting the behaviour of meteoroids which enter the Earth's atmosphere, to ensure spacecraft safely survive atmospheric reentry, and for the design of high-speed aircraft and missiles.

  7. Ballistic missile flight phases - Wikipedia

    en.wikipedia.org/wiki/Ballistic_missile_flight...

    The boost phase is the portion of the flight of a ballistic missile or space vehicle during which the booster and sustainer engines operate until it reaches peak velocity. . This phase can take 3 to 4 minutes for a solid rocket (shorter for a liquid-propellant rocket), the altitude at the end of this phase is 150–200 km, and the typical burn-out speed is 7 k

  8. Reentry capsule - Wikipedia

    en.wikipedia.org/wiki/Reentry_capsule

    A reentry capsule is the portion of a space capsule which returns to Earth following a spaceflight. The shape is determined partly by aerodynamics ; a capsule is aerodynamically stable falling blunt end first, which allows only the blunt end to require a heat shield for atmospheric entry .

  9. Hypersonic glide vehicle - Wikipedia

    en.wikipedia.org/wiki/Hypersonic_glide_vehicle

    Chinese DF-ZF hypersonic glide vehicle mounted on the DF-17 ballistic missile. American Long-Range Hypersonic Weapon being deployed at the Cape Canaveral Space Force Station. A hypersonic glide vehicle (HGV) is a type of warhead for ballistic missiles that can maneuver and glide at hypersonic speed. It is used in conjunction with ballistic ...
