[文摘]:Lift to drag ratio (L/D) requirements and stagnation point heating have been examined for a variety of probable entry conditions and vehicle configurations. It is found that vehicles with an L/D of 0.5 or more provide a corridor width of at least 0.7 degrees while keeping the peak deceleration load below 5 g for approach velocities up to 14.5 km/s. It is shown that stagnation point peak heating rates and integrated heat load critically depend on both entry velocity and ballistic coefficient. For the most severe cases under consideration, peak heating and integrated heat load are five times greater than those encountered by Apollo but within the range of experience for unmanned vehicles.

[标题]:Modeling of pulsed gas flow laser
[作者]:OFFENHAEUSER FRIEDRICH
[文摘]:Very complex simulation problems, occurring in the description of pulsed gas flow lasers were modeled. The fundamentals of the laser model are described. The computer code has the property that the type of laser is specified by a data file only. Hence, the laser model can be applied without changes of the computer program to all gas flow lasers whereby gas flow, optical axis, and a possible electrical excitation act perpendicularly to each other.
