    On J , two days before the launch of the Apollo 11 mission, NASA's Lewis Research Center (now Glenn) issued this news release. The release highlights the center's role in the Apollo program and outlines the team effort required to accomplish a manned mission to the moon. For a transonic body, the area rule is applied by subtracting from, or adding to, its cross-sectional area distribution normal to the air stream at various stations so as to make its cross-sectional area distribution approach that of an ideal body of minimum drag; for a supersonic body, the sectional areas are frontal projections of areas.

    A scramjet (supersonic combustion ramjet) is a variant of a ramjet airbreathing jet engine in which combustion takes place in supersonic in ramjets, a scramjet relies on high vehicle speed to compress the incoming air forcefully before combustion (hence ramjet), but whereas a ramjet decelerates the air to subsonic velocities before combustion, the airflow in a scramjet is supersonic. Flow visualization is provided through color maps of local Mach number, density, pressure, and temperature, including streamline plots. An aerodynamic force line instantly reveals the center of pressure of any configuration. MicroCFD can model vehicles in ground effect through a 2D simulation of flow along their centerline.

    Hypersonic flight has been with us since 22 September , when Robert M. White flew the North American X at mph at an altitude of , ft —a Mach number of ! This remarkable achievement was accomplished over six decades due to intensive research and development by a large number of scientists and by: Telemetry is the collection of measurements or other data at remote or inaccessible points and their automatic transmission to receiving equipment for monitoring. The word is derived from the Greek roots tele, "remote", and metron, "measure".Systems that need external instructions and data to operate require the counterpart of telemetry, telecommand.

TRANSONIC PRESSURE DISTRIBUTIONS OVER PROTUBERANCES AND ADJACENT AREAS IN PROXIMITY TO THE NOSE OF A LAUNCH VEEICLLE By James A.

Blackwell, Jr. Langley Research Center A wind-tunnel investigation was conducted over a Mach number range from to to determine the pressure distributions over protuberances and adjacent areas in proximity to the nose of a launch. Transonic flow in the wake of a generic space launch vehicle is investigated using Improved Delayed Detached-Eddy simulations on quasi-structured, partially unstructured and hybrid grids.

Launch vehicles are typically designed to fly at very low angles of attack. Nevertheless, even at such low angles of attack, the lateral (CFD) group (Basso, Antunes and Azevedo, a), together with additional computational resources available in the country, have made possible the analysis of almost realistic E.

A boilerplate spacecraft, also known as a mass simulator, is a nonfunctional craft or payload that is used to test various configurations and basic size, load, and handling characteristics of rocket launch is far less expensive to build multiple, full-scale, non-functional boilerplate spacecraft than it is to develop the full system (design, test, redesign, and launch).

/5(). The LAIOP (Launch Vehicle Ignition Overpressure and Liftoff Acoustic Environments) program predicts the external pressure environment generated during liftoff for a large variety of rocket types. These environments include ignition overpressure, produced by the rapid acceleration of exhaust gases during rocket-engine start transient, and launch acoustics, produced by turbulence in the rocket Author: Marshall Space Flight Center.Wind Load Calculator.

In order for a structure to be sound and secure, the foundation, roof, and walls must be strong and wind resistant. When building a structure it is important to calculate wind load to ensure that the structure can withstand high winds, especially if the building is located in an area known for inclement weather.Piles are used; as anchors, to raise structures above ground or to prevent movement (subsidence) in structural foundations.
