Projectile launch detector, and associated projectile and launcher assembly

A projectile launch detector, comprising:

• a body arranged along a first axis;
• a mast extending along the first axis, said mast comprising a first and a second end, respectively arranged inside and outside the body;
• and
• a blade secured to the second end of the mast and extending radially relative to said mast,
• said blade including:
• first and second opposite faces, parallel to the first axis;
• and an end surface, substantially perpendicular to the first axis and opposite the body;
• the mast configured to slide relative to the body along the first axis, between a retracted configuration and a deployed configuration, the blade being axially closer to the body in the retracted configuration than in the deployed configuration;
• the mast further configured to pivot relative to the body about the first axis, between a first and a second angular position;
• and
• the detector further comprising:
• a first elastic return element, configured to return said mast to the deployed configuration relative to the body;
• a first sensor configured to determine whether the mast is in the retracted configuration or in the deployed configuration;
• a second elastic return element, configured to return said mast to the first angular position relative to the body;
• and
• a second sensor configured to determine whether the mast is in the first or the second angular position.
