“…A preliminary cost budget has been carried out by exploiting a modified version of the model developed by Koelle and implemented by Snead [26]. The model is based on a statistical correlation between the vehicle mass and its development and production costs, expressed in terms of work years and takes into account the Technologic Readiness Level (TRL) of each component.…”

a b s t r a c tIn the present work a preliminary performance study regarding a small hypersonic airplane named HyPlane is presented. It is designed for point-to-point medium range hypersonic trip, within the "urgent business travel" market segment. The vehicle is also consistent with long duration suborbital space tourism missions, in the frame of the Space Renaissance (SR) Italia Space Tourism Program. The design of such a hypersonic airplane is based on the concept of integrating available technologies developed for aeronautical and space atmospheric re-entry systems.The vehicle, characterized by high aerodynamic efficiency and low wing loading and powered by Turbine Based Combined Cycle (TBCC) engines plus a throtteable Rocket, is able to produce a reduced sonic boom and to perform Horizontal Takeoff and Horizontal Landing (HTHL) on runways.Aerodynamic and propulsive performances for the different flight regimes encountered during the missions are studied. Aerodynamic heating effects are analyzed, in order to identify suitable structures and materials design to sustain the hypersonic flight conditions. Different flight paths are also investigated, including hypersonic cruise and suborbital parabolic trajectories, which provide Space tourists with the opportunity of long duration missions, offering short and repeated periods of low-gravity, in the high stratosphere where a large view of the Earth is ensured.

“…Conceptual design studies undertaken at the Air Force Aeronautical Systems Center (Wright-Patterson Air Force Base, Ohio) have generated concepts for fullyreusable Earth-to-orbit space access systems-referred to herein as aerospaceplanes-using TRL 6-9 technologies. 1,2 Figure 2 depicts the general system configuration used in these studies. This is a two-stage, rocket-powered, vertical-takeoff, horizontal-landing system that carries cargo in an externallymounted container or passengers in an externally-carried 6-10 passenger aerospaceplane.…”

Key elements of the needed near-future, integrated, spacefaring logistics infrastructure are space-based, fully-reusable space logistics vehicles to provide transportation for passengers and cargo. This paper addresses the conceptual design of two such reusable spaceships using near-term technologies. The first is a space tug designed to support logistics operations in Low Earth Orbit (LEO). This space tug is sized to provide materiel handling, cargo transport, and passenger transport capabilities to support the construction and operation of orbiting logistics facilities and large spaceships. The second is a space ferry designed to transport cargo and passengers throughout the Earth-Moon system. This paper defines the assumptions and mission requirements used in the conceptual design of these two spaceships, summarizes the required Delta-V and maneuvering capabilities, assesses the technology maturity of the enabling technologies, summarizes the mass property estimates, provides illustrations of the conceptual designs, and provides examples of their use and integration into a near-future, integrated, spacefaring logistics infrastructure. The intent of this paper is to describe how current technologies can enable "aircraft-like" safe and routine transport of passengers and cargo within the Earth-Moon system.

In the present work a preliminary study on a small hypersonic airplane for a long duration space tourism mission is presented. It is also consistent with a point-to-point medium range (5000 km) hypersonic trip, in the frame of the "urgent business travel" market segment. Main idea is to transfer technological solutions developed for aeronautical and space atmospheric re-entry systems to the design of such a hypersonic airplane. A winged vehicle characterized by high aerodynamic efficiency and able to maneuver along the flight path, in all aerodynamic regimes encountered, is taken into consideration.Rocket-Based Combined Cycle and Turbine-Based Combined Cycle engines are investigated to ensure higher performances in terms of flight duration and range. Different flight-paths are also considered, including sub-orbital parabolic trajectories and steady state hypersonic cruise. The former, in particular, takes advance of the high aerodynamic efficiency during the unpowered phase, in combination with a periodic engine actuation, to guarantee a long duration oscillating flight path. These trajectories offer Space tourists the opportunity of extended missions, characterized by repeated periods of low-gravity at altitudes high enough to ensure a wide view of the Earth from Space.
