    A method for the implementation of integrated three-degree-of-freedom constrained entry guidance for reusable launch vehicle is presented. Given any feasible entry conditions, terminal area energy management interface conditions, and the reference trajectory generated onboard then, the method can generate a longitudinal guidance profile rapidly Cited by: 7. The return to earth consists of three phases--Entry, Terminal Area Energy Management (TAEM), and Approach and Landing. The Space Shuttle is programmed to fly all three phases of flight automatically, and under normal circumstances the astronaut-pilot takes manual control only during the Approach and Landing : Bradley Burchett.

Thus, automated guidance and control systems are a critical.

    Suppose the entry flight ends at the terminal area energy management interface, the terminal altitude h f, terminal velocity v f and the range to the target S f should be: (12) h f = h T A E M, v f = v T A E M, S f = S T A E M. Control constraint is also an important part of the path constraints: (13) α ∈ [α min, α max], υ ∈ [υ min, υ Cited by: 8. In the transition phase, the angle of attack continues to ramp down, reaching approximately 14° at the entry terminal area energy management (TAEM) interface, at an altitude of approximat feet, a velocity of 2, fps, and a range of 60 nm from the runway. Control is then transferred to TAEM guidance.

As the TAEM target altitude is approached, entry guidance transitions from the high a of about 40 ° to the TAEM level of about 10 °. Speedbrake during entry is to a preprogrammed profile to assist attitude control and is not used for guidance.

A derivation and explanation of logic and equations are provided as a supplement to the well documented guidance computation requirements contained within Author: Thomas E.

management of the energy during final phases of re-entry close to the ground—otherwise called terminal area energy management—critical for a safe landing. The Orbiter performed as a glider during re-entry, thus its mass properties had to be well understood to ensure that the Flight Control System could control the vehicle and reach the required.

Descent guidance and mission planning for space shuttle. 14 ft/s delivers the Orbiter to the terminal area energy management (TAEM) interface ( ft/s) The Space Shuttle entry. In the entry mode, the compass card heading indicates the magnetic heading of the vehicle’s relative velocity vector.

In terminal area energy management and approach, the compass card indicates magnetic heading of the body X axis. In the entry mode, the course deviation indicator is driven to zero with no flag. The entry phase of a Shuttle mission lasts from the so-called entry interface at about ft to the terminal area energy management (TAEM) interface at ft.

During that time, the Shuttle decelerates from orbital speed (Mach 26) to supersonic speed (Mach ) and changes from a ballistic flight trajectory to an aerodynamical glide. In the transition phase, the angle of attack continues to ramp down, reaching approximately 14 at the entry terminal area energy management (TAEM) interface, at an altitude of approximat feet, a velocity of 2, fps, and a range of 60 nm from the runway.

The Space Shuttle program is the major segment of NASA's National Space Transportation System (NSTS) managed by the Office of Space Flight (OSF) at NASA Headquarters in Washington, D. The office is headed by an Associate Administrator who reports directly to the NASA Administrator and is charged with providing executive leadership, overall direction and effective accomplishment of the Space Shuttle.

The Heading Alignment Circle was used by the Shuttle as a tool to assist with managing energy while guiding it to line up for final approach to the runway.

The Shuttle performed a turn following the HAC when it intercepted the circle at ab0. Full text of "Space shuttle digital flight control system" abort once around; on-orbit operations, entry, terminal area energy management (TAEM) ; and approach and landing.

The FCS is complicated in that it must perform the functions to fly the Shuttle as a boost vehicle, as a spacecraft, as a reentry vehicle, and as a conventional aircraft. In the transition phase, the angle of attack continues to ramp down, reaching the approximately degree angle of attack at the entry Terminal Area Energy Management (TAEM) interface, at approximat feet altitude, 2, feet per second, Mach and 52 nautical miles (59 statute miles) from the landing runway.

Control is then transferred to.Before the space shuttle, most entry vehicles were relatively simple, blunt shapes with no aerodynamic control surfaces. work was conducted for several years in the simulator to investigate the terminal area energy management concepts designed by engineers at JSC.

It begins at ft altitude, at a speed of Mach and about 60 NM from the runway.

During this phase RCS thrusters are step by step inhibited and the crew and associated automated systems perform energy and track management .
