Demonstrator Aircraft Conceptual Designs
While the X-Wing hardware was being developed the design team was working on designs for the demonstrator aircraft. Numerous approaches were investigated including the use of the convertible engine to provide both shaft power for the X-Wing rotor and compressor and thrust for the high-speed fixed wing mode, as shown in the first illustration of this section. Another approach was to use conventional turboshaft engines to power both the X-Wing systems plus conventional propellers. Such a design with pusher propellers is shown below.
The following illustration shows the need for both leading and trailing edge blowing. In rotary wing mode, air is blown out the trailing edges of the blades. In the fixed wing mode, two of the blades are now flying “backwards” with blowing now required on what was the leading edge. During conversion the aerodynamics get much more complicated, with circulation control blowing required out of both the leading and trailing edges at the same time.
The Boyesen Power X-Wing is the simplest, most economical way to maximize the efficiency of your carbureted 2 stroke's or 4 stroke's intake system. The Power X-Wing increases air speed (velocity) at all throttle settings. It does this by streamlining incoming air and works to better prepare the TURBULENT air for entry into the carburetor. Simply stated, increasing air speed and density are the two most important aspects of gaining performance in your intake system. That is precisely what the Power X Wing delivers.
In order to fully understand the performance benefit that the Power X Wing delivers, a rider will first need to be aware of the importance of air velocity and how it relates to your engine’s ability to create horsepower and torque - especially at low RPMs. As air velocity (speed) increases the more viscous (dense) it becomes, causing the air to display characteristics which are more like a fluid. The effective air velocity creates an action known as fuel shearing, splitting the droplets of fuel into a finer gas-like mist. With the two different substances becoming more like one another, your engine will receive a superior air/fuel mixture. This in turn, helps your engine maximize its potential for making torque and horsepower.
