Part 1: The Concept<br />
According to Pr<strong>of</strong>essor J. Gordon Leischman: "A <strong>hybrid</strong> helicopter implies the use <strong>of</strong> a wing<br />
(<strong>hybrid</strong>ized lift) or the addition <strong>of</strong> a separate source <strong>of</strong> thrust for propulsion (<strong>hybrid</strong>ized<br />
thrust). The aim is to relieve the rotor <strong>of</strong> its normal lift and propulsion functions. This can be<br />
achieved by using a wing and/or auxiliary propulsion."<br />
Combining hover and high-speed horizontal flight capabilities is an old dream <strong>of</strong> airplane and<br />
helicopter designers. To cover the whole flight spectrum and all the missions <strong>of</strong> different<br />
aircraft with the same flying machine is one <strong>of</strong> the aeronautical industry's biggest challenges.<br />
