This paper presents an attitude control algorithm for a Reusable Launch Vehicle (RLV) with a low lift/drag ratio (L/D < 0.5), in the presence of external disturbances, model uncertainties, control output constraints and the thruster model. The main novelty of proposed control strategy is a new combination of the attitude control methods included backstepping, dynamic inversion and adaptive cont...

Apollo powered descent guidance (APDG) law enabled lunar module to land on the Moon successfully. Since then, in past 50 years, APDG and several of its variants have been used numerous planetary landing studies missions. As formulation does not consider drag force, is typically for rarefied environments like Mars. In this paper, we extend application atmospheric by aiding it with an acceleratio...

A tank and intertank sizing tool that includes effects of major design drivers, and which allows parametric studies to be performed, has been developed and calibrated against independent repzresentative results. Although additional design features, such as bulkheads and field joints, are not currently included in the process, the improved level of fidelity has allowed parametric studies to be p...

In this section, we examine the space launch needs of U.S. military, civil, and commercial space sectors. The potential development and operating costs for a small fleet of military TAVs are reviewed and compared with the costs associated with a small expendable launch vehicle. The potential development costs for commercial RLVs are also briefly reviewed. Next, we examine U.S. launch policy and...

According to the symmetrical characteristics of a new type Reusable Launch Vehicle (RLV) in recovery phase, we studied basic aerodynamic model data Starship and with rudder deflection, causes its coefficients are expounded. At same time, analyzed stability maneuverability. flying quality requirements, lateral-directional return phase at high angle attack is analyzed. Finally, lateral heading co...

Abstract The EU has deemed it crucial to maintain its own independent access space. To foster the European industry competitiveness, cost of launch systems needs be reduced and flexibility improved. development reusable vehicle (RLV) is currently changing global market space transportation promising immense savings. Within this context, MT Aerospace been investigating configurations possible so...

This paper will describe recent advances in ISHM technologies made through collaboration between NASA and industry. In particular, the paper will focus on past, present, and future technology development and maturation efforts at the Jet Propulsion Laboratory (JPL) and its industry partner, Northrop Grumman lntegrated Systems (NGIS). Through numerous collaborations in ISHM technology developmen...

the amount of analysis and testing required per mission must be reduced over that performed for the partially re-usable Space Shuttle. A goal for future RLV flight control is to design and test the flight control system to operate within a prescribed flight envelope and loading margin, and requiring only payload/fuel parameters and “route” to be specified for a given mission. It has been estima...

While NASA’s current next-generation launch vehicle research has largely focused on advanced allrocket single-stage-to-orbit vehicles (i.e. the X-33 and it’s RLV operational follow-on), some attention is being given to advanced propulsion concepts suitable for “next-generation-and-a-half” vehicles. Rocketbased combined-cycle (RBCC) engines combining rocket and airbreathing elements are one cand...
