Corset System ©
Developed at the end of the 2000s, the appearance of variable configuration wings is a real revolution in the weight-shift controlled aircraft, the Corset technology invented by Gilles BRU open a whole new flight domain to pilots.
The pursuit of performance has brought the generalization of trim systems which make it possible to vary the cruising speed.
The flex-wing wings roll reaction is proportional to their flight speed, making the wing unwieldy at low speeds and conversely too sensitive at high speeds. This implies that conventional design fast wings are unable to make slow approaches and land in a short distance in turbulent conditions.
The Corset system patented by Air Creation is the answer to this problem:
It combines exceptional ease of use to remarkable effectiveness. It allows to control the cruising speed and at the same time adapt the wing geometry to this new speed. By acting on the billow, the twist and the central wing profile, it reconfigures itself like those of a bird.
The control of the corset is as easy to use as a conventional trimmer, it acts directly on the wings tension to control the keel to the wing tip using a hoist connected to a hand crank attached to a tapered roller and control line.
Slow flight :
Either the approach, the landing phases or to increase the rate of climb, a slow speed range is recommended.
In this case the tension is released, it has the effect of twisting the wing tip, increasing the central profile prominence as well as the billow. This action decreases central reflex and move forward the center of thrust. All these modifications to the wing profile, makes it possible to decrease the cruising speed but also to improve the maneuverability in roll, safe maneuvering at large incidences and increase the wing lift coefficient.
high speeds :
In order to travel, to cruise or simply to counter strong winds, it is more convenient to adopt a high-speed range.
For this we increase the tension which has the effect of reducing the twist at the wing tip, decreasing the central profile prominence as well as the billow. This action increases the central reflex and retract the center of thrust. All these modifications to the wing profile, make it possible to obtain a high cruising speed but also reduce the drag attributed to the wing, ensuring the perfect pitch preservation and improve the roll stability.
