Read News Release 09-04 NASA Dryden's NF-15B tail number 837's canards are tilted down during a pre-flight control check prior to a Lancets project flight. NASA's Dryden Flight Research Center accomplished a series of flight tests to measure shock waves generated by an F-15 jet in support of the Lift and Nozzle Change Effects on Tail Shock, or Lancets, project. The research flights, flown December 2008 through January 2009, were aimed at providing data to help validate computer models that could be used in designing quieter supersonic aircraft.
