The present paper is based on an extreme interest in technological demonstrators of future hypersonic transatmospheric planes. Technological demonstrators provide a good set of information with a high benefit to cost ratio. This fact is confirmed by the increasing number of technological demonstrators and by the study and development of smaller technological demonstrators conceived to carry out bigger ones. Affordability is certainly an important key in new demonstrators' development but many times the target of affordability is reached only if new, unconventional concepts are developed and applied. Our Research Group has developed a first idea concerning the use of a standard air to air missile as basis element of a demonstrators' family. In this way two goals can be reached: (1) thanks to a modular conception, which allows to investigate several aerodynamic configurations by simply (2) the utilization of existing items, like the basic element of the demonstrator, the air-to-air missile which holds In order to minimize the development effort, that is the modification of the missile internal layout to accomplish the new and unusual role, another interesting idea has been conceived. It concerns the study of a smaller not powered technological demonstrator attached to the air to air missile in central position, being the missile now used as a big booster. The poorer aerodynamic characteristics and the practical impossibility of reusing the missile have to be evaluated and compared with the easier development. Many different configurations of both concepts have been investigated. The simulations' outcomes are attractive and both projects seem to be feasible. At the moment these ideas are considered for a pre-demonstrator of a future demonstrator of considerable size which is now under development by Italian Aerospace Research Centre (CIRA) and Aerospace Industry.
