1973-1976
Dynamic wind tunnel simulation of a highly augmented flexible model aircraft with canard control surfaces. The test rig and model aircraft demonstrated open- and closed-loop control laws for variable stability functions, rigid body gust alleviation, and elastic mode suppression systems (Project BASE).

Hyplane: a single-stage suborbital aerospaceplane - CEAS Space Journal

This paper has the aim to report the status of the HYPLANE project to date. HYPLANE is a horizontal take-off and landing Mach 4.5 bizjet-size aerospaceplane conceived by Trans-Tech and University Federico II of Naples and under study within the industrial-academic ecosystem of the Campania...
