Walter Meyer Quotes & Sayings

Nagler-Rolz helicopter (unspecified type) Two types of ultra-light helicopter were designed by Bruno Nagler. Each of these could be strapped to a man's back. The first, for which no designation has been reported, has a single rotor, and a small engine enclosed in a fairing is mounted on an extension of the rotor on the opposite side of the hub. The motor drives a shaft which is housed inside the blade and, in turn, through bevel gearing, drives two small propellers in opposite directions. The propellers are located at the centre of pressure, one at the leading-edge and one at the trailing-edge of the blade. Nagler-Rolz NR — Walter Meyer
