Nasa set to test cleaner, quieter wings
14 May 2014
Current plane wing designs create noise pollution and aren’t very efficient. Are wings that change shape a better solution?
In place of the jet’s old flaps, Nasa engineers are fitting a new bendable wing control surface known as an Adaptive Compliant Trailing Edge (ACTE). The technology’s key advantage is that it eliminates the gaps in wing edges seen in traditional hinged flaps, replacing them with a gently contoured transition.
- Technological modelling: Use this and other examples to describe examples to illustrate how prototypes were tested to evaluate a technological outcome’s fitness for purpose. (level 4)
- Technological products: Use this and other examples to suggest why the materials used in particular technological products were selected (level 2). Discuss examples to illustrate how decisions about material selection take into account the composition of the material and the specifications of the product. (level 5)
