The orbital tug is perhaps the most common, yet least glamorous spacecraft. The shuttles slingships, fiercely clawing their way out of the gravity well, are dramatic, but never get higher than LEO, whereas most orbital activities, such as the space stations and spacedocks, take place at higher orbits.
Thermal Protection Requirements for Near-Earth Aeroassisted Orbital Transfer Vehicle Missions Thermal Design of Aeroassisted Orbital Transfer Vehicles August Design study of a slant-nose-cylinder aeroassisted orbital transfer vehicleCited by: The concept of aeroassisting for orbital transfer has been recognized as one of the critical technologies for pioneering the space frontier.
In space transportation systems, aeroassisting (or aerobraking), defined as the deceleration resulting from the effects of atmospheric drag upon a vehicle during orbital operations, opens new mission opportunities, especially with regard to the.
The objectives of the Orbital Transfer Vehicle (OTV) Concept Definition and Systems Analysis study, conducted by General Dynamics Space Systems Division under company funds with data provided to NASA-MSFC, were to define the requirements, concepts, and evolutionary approaches for development of an OTV for reusable operations to GEO and beyond, including manned access; assess the.
Description. The present volume is devoted to the thermophysics of aeroassisted orbital transfer vehicle (AOTVs). As its title suggests, it is truly a progress volume for it illustrates the recent advances and current thinking with regard to AOTVs.

Aeroassisted orbital transfer (AOT) combines space maneuvers and atmospheric maneuvers so as to achieve propellant savings vis-à-vis purely propulsive maneuvers, albeit at the expense of high heating rates during the atmospheric pass.
Of critical importance is the study of optimal trajectories; equally important is the development of guidance schemes in view of the precision. As an example, according to Miele, the fuel saving for a planar or quasi-planar aeroassisted transfer between a geostationary orbit and low Earth orbit can reach 60% of the fuel needed by Hohmann equivalent transfer.
Atmospheric density variations, vehicle area-to-mass ratio, aerodynamical coefficients are the main causes of the deviations in. For the case of a manned return to the Moon (build-up of a lunar base included) this paper investi- gates the use of lunar oxygen as propellant com- ponent for an aeroassisted orbital transfer vehicle for interorbital transfer and for a lunar bus for lunar descent/ascent.
Furthermore, the fluorination as a possible production process is outlined. Aero-assisted orbit transfer vehicles have the potential for significantly reducing the fuel requirements in certain classes of orbit transfer operations. Level Two involves Interactive Services such as the ISS, in-space attachment of re-boost packages, orbit transfer vehicles and common launchers.

The three phases of the mission are illustrated on Figure 1. Low orbit MODEL EQUATIONS The spacecraft is supposed to be axisymmetric and the data for its model are taken from an AFE type vehicle (Miele et a/., a, b), (Gamble et a/., ).
Thus, the aerodynamic forces on the vehicle are limited to the drag and lift. The attitude control of a spacecraft with a moderate lift/drag ratio during an aeroassisted orbit transfer is considered. The system is non linear, and can be transformed in a linear time-varying one in function of the aerodynamic velocity of the vehicle and the atmospheric density, the purpose of this work is to use adaptive techniques to control the attitude of the vehicle, so that the.

Fuel-optimal trajectories for aeroassisted coplanar orbital transfer problem Abstract: The optimal control problem arising in coplanar, orbital transfer employing aeroassist technology is addressed. The maneuver involves the transfer from high Earth orbit to low Earth orbit by means of the atmosphere with the object of minimizing the total fuel.
Aeroassisted orbital transfer introduces a strong coupling between the trajectory design and the vehicle design; a trajectory that minimizes fuel mass without attention to heating may require the.

Aeroassisted Orbital Transfer Vehicles (AOTV) become relevant to meeting the crew transfer functional requirement. Results are shown for several vehicle classes along with the impacts of varied mission parameters such as crew-day, and delta-velocity (V) requirements.
CTV Element Tradespace. vehicle as an aeroassisted reusable vehicle is economically justified, even in the most modest projected mission scenarios. We believe that, even though it is difficult to justify on a discounted life cycle cost basis, the lower operational cost of space based OTV missions and the ancillary operational benefits justify investment in space basing.

The study goal was to examine the mission requirements and provide a decision data base for future programmatic.
Thermodynamically nonequilibrium airflow past blunt bodies at high supersonic velocities is investigated with allowance for nonequilibrium dissociation and recombination reactions, vibrational-dissociative interaction and the reciprocal effect of the reactions on vibrational relaxation. Simplified Navier-Stokes equations, which take into account the structure of the viscous shock, are used for.
