Abstract An investigation into the calibration of the Shuttle Entry Air Data System (SEADS) has been conducted for the purpose of obtaining angle of attack and sideslip during ascent powered flight.

The calibration methodology involves modeling a modified newtonian pressure distribution, corrected for interference, around the orbiter by: 3. Shuttle Entry Air Data System. Accurate aerodynamic research requires precise knowledge of vehicle attitude and state. This information, commonly referred to as air data, includes vehicle angle of attack, angle of sideslip, free-stream dynamic pressure, Mach number and total pressure.

The SEADS system (Shuttle Entry Air Data System) is being developed to provide research quality hypersonic (M greater than ) air data. SEADS will accomplish this through the instrumentation of the orbiter's baseline nose cap. The Shuttle Entry Air Data System (SEADS) is the implementation of a new concept in air data systems, with application to entry vehicles.

AIR DATA SYSTEM. Two air data probes are located on the left and right sides of the orbiter's forward lower fuselage. During the ascent, on-orbit, deorbit and initial entry heat load environment phases, the probes are stowed inside the forward lower fuselage.

Six additional ports were mounted in other nearby locations. These sensor ports were made from an exotic, high temperature metal named, in a strange coincidence, columbium. It also provided data to validate algorithms developed for the shuttle entry air data system designed at NASA Langley.

Data were obtained for Mach numbers between andfor angles of attack up to deg, and for sideslip angles up to deg. With careful calibration, a flush air data system with all flush orifices can provide accurate air data information over a large range of flow angles. Ting, P. C, W. Rochelle, and D.

Introduction. The design concept of the flush air data sensing system (FADS) was presented by the American National Aeronautics and Space Administration in the s in order to meet the control requirements of the space shuttle [1,2].FADS has some significant advantages over traditional sensors [3,4], including the higher measurement accuracy and lighter equipment weight.

Another less obvious change to Columbia is a new nose cap to house the Shuttle Entry Air Data System (SEADS) experiment. A number of pressu re sensors inside the nose cap will provide aerodynamic flight characteristics during reentry. Another modification was made to accommodate the Shuttle Upper Atmosphere Mass Spectrometer (SUMS) experiment.

The Space Shuttle avionics system controls, or assists in controlling, most of the Shuttle systems including: automatic determination of the vehicle's status and operational readiness; implementation sequencing and control for the solid rocket boosters and external tank during launch and ascent; performance monitoring; digital data processing; communications and tracking; payload and system.

facilitate access to the data base by the analysts. The Space Shuttle wind tunnel test data base was archived using UNIX based work stations and was saved in an ASCII format on an 8 mm cartridge tape. To facilitate the use of the digital data base tape, a user's manual has been developed and is presented as Volume 2 of this report.

Inthe Space Shuttle Program selected an off-the-shelf Global Positioning System (GPS) receiver to eventually replace the three Tactical Air Navigation units on each space shuttle orbiter. A proven, large production base GPS receiver was believed to be the key to reducing integration, certification, and maintenance costs.It is Shuttle Entry Air Data System.
