Abstract
An aerial vehicle having a fuselage having a front portion provided with an optronic sensor and a cover for protecting the sensor, the cover being removably mounted and held on the fuselage by at least one retaining member arranged to retain the cover against aerodynamic forces exerted on the cover during flight. The aerial vehicle includes a member for deactivating the retaining member and an electronic control circuit arranged to control the deactivation member in flight to allow the cover to be ejected.
Claims14
An aerial vehicle comprising:
- a fuselage having a front portion provided with an optronic sensor;
- a cover for protecting the optronic sensor, the cover being removably mounted and held on the fuselage by at least one retaining member arranged to retain the cover against aerodynamic forces exerted on the cover during flight, the cover comprising, facing the optronic sensor, a uniform internal surface making it possible to calibrate the optronic sensor before the cover is ejected;
- a deactivation member for deactivating the retaining member;
- and
- an electronic control circuit arranged to control the deactivation member in flight so as to allow the cover to be ejected.
