Nagler XNH I Heliglider / XNH-2 Heligyro
This, the first rotorcraft (1952) which Nagler designed after his arrival in the United States, was of the 'strap-on' variety. Its intended use was to cross rivers or other obstacles. The required height was to be reached by power from six solid-propellant rockets, fired in pairs and providing a 9kg thrust for about twenty seconds. Slow descent was ensured by the auto-rotation of the rotor. The six rockets could be replaced for later use.
The wearer's legs were to be the landing gear.
With the addition of a 2 cylinder opposed engine driving a pusher prop also in 1952, the XNH-1 was re-designated XNH-2 Heligyro.
