The International Space Station flight control positions used by NASA in Houston are different from those used by previous NASA programs. These differences exist primarily to stem the potential confusion that might otherwise follow from conflicting use of the same name in two different rooms during the same operations, such as when the space ...
In many flight dynamics applications, the Earth frame is assumed to be inertial with a flat x E,y E-plane, though the Earth frame can also be considered a spherical coordinate system with origin at the center of the Earth. The other two reference frames are body-fixed, with origins moving along with the aircraft, typically at the center of gravity.
Flight dynamics calculations are handled by computerized guidance systems aboard the vehicle; the status of the flight dynamics is monitored on the ground during powered maneuvers by a member of the flight controller team known in NASA's Human Spaceflight Center as the flight dynamics officer, or in the European Space Agency as the spacecraft ...
In orbital mechanics, a porkchop plot (also pork-chop plot) is a chart that shows level curves of equal characteristic energy (C 3) against combinations of launch date and arrival date for a particular interplanetary flight. [1] The chart shows the characteristic energy ranges in zones around the local minima, which resembles the shape of a ...
For Space Shuttle missions, in the firing room at the Launch Control Center, the NASA Test Director (NTD) performed this check via a voice communications link with other NASA personnel. The NTD was the leader of the shuttle test team responsible for directing and integrating all flight crew, orbiter, external tank/solid rocket booster and ...
Flight dynamics in aviation and spacecraft, is the study of the performance, stability, and control of vehicles flying through the air or in outer space. [1] It is concerned with how forces acting on the vehicle determine its velocity and attitude with respect to time.
Ludwig Prandtl Ring (1978); Langley Gold Medal (1981); Fluid Dynamics Prize (1986); NAS Award in Aeronautical Engineering (For his major contributions to aeronautics, including his supersonic area rule, discovery of the value of wing sweep in attaining supersonic flight, and application of the Heaviside Calculus to flight dynamics., 1990)
Most aircraft trimmed for straight-and-level flight, if flown stick-fixed, will eventually develop a tightening spiral-dive. [2] If a spiral dive is entered unintentionally, the result can be fatal. A spiral dive is not a spin; it starts, not with a stall or from torque, but with a random perturbation, increasing roll and airspeed.
