NASA has designed a new plane that can reduce aircraft noise by as much as 30 per cent on takeoff and landing.

The innovation lies in a new flap design - traditional flaps, when lowered, create gaps between the forward edge, the sides of the flaps and the wing surface.

Wing - Configuration - Level - Control - Wing

But a flexed wing configuration allows a level of control over how and where the wing responds to wind gusts, significantly reducing airframe noise during takeoff and landing, and potentially saving on fuel.

The goal of the project, called The Adaptive Compliant Trailing Edge flight test project (ACTE), is to investigate the capabilities of shape-changing surfaces and determine if advanced flexible trailing-edge wing flaps can improve aircraft aerodynamic efficiency, enhance fuel economy and reduce airport noise generated during takeoff and landings.

Phase - Flap - Design - Aircraft - Noise

Phase I showed that the new flap design can reduce aircraft noise, and phase II, which is expected to continue this fall and conclude at the end of the year, will build on the research and data collected from tests of the flap being locked in different positions in flight during the first phase.

The second phase, taking place at the NASA Neil A. Armstrong Flight Research Center in Edwards, California, will also test the technology at higher speeds and research how the flaps impact aerodynamics forces that could improve fuel efficiency.

'ACTE has tremendous potential to increase airframe efficiencies,' said Kevin Weinert, ACTE project manager.

'We have tested the flap at six...
