Bracing for Fuel-Efficient Flight

A model of the Transonic Truss-Braced Wing aircraft is seen here installed for testing in the Unitary Plan Wind Tunnel at NASA’s Ames Research Center in California. A model representing just half the airplane, sliced from nose to tail, is used so that the tunnel can fit a larger-scale model holding hundreds of sensors to record data during the test. At about 11 feet long and 7.5 feet from floor to wing tip, this model is 9 percent of the size of the full-scale aircraft. Author: Abby Tabor, NASA's Ames Research Center
