Aerotecnica Missili & Spazio is the journal of the Italian Association of Aeronautics and Astronautics, AIDAA, founded in 1920. Aerotecnica Missili & Spazio aims at publishing contributions in the field of aerospace sciences, technologies and systems. This includes disciplines in the area of mechanical sciences like flight mechanics, aerodynamics, propulsion, aerothermochemistry, structures and materials, astrodynamics as well as other disciplines such as telecommunication, navigation, control, electronics, informatics and all aspects related to ground testing and operations when applied to the aerospace field. Contributions regarding the aeronautical or space vehicle as an engineering system are particularly welcome. Also in covering the basic disciplines here above recalled, submitted manuscripts should always address the aerospace missions and systems rather than strictly specialized topics more appropriate to a discipline oriented journal. Papers dealing with overall exploitation and management of aerospace systems and on the impact of scientific applications on system design and operation, as for example in the fields of remote sensing, microgravity, geodesy, exploration and astrophysics, are encouraged too.
