C-140 JetStar

This C-140 JetStar was flown by NASA's Dryden Flight Research Center,
Edwards, California, from 1964 to 1989 in a variety of projects applicable
to civilian aircraft. Built by Lockheed, the aircraft-NASA 814-was used in a
laminar flow study to help develop methods of designing more efficient
aircraft wings.

The JetStar was later used as a testbed to investigate acoustic
characteristics of a series of subscale advanced design propellors which
featured blades that curved rearward. The aircraft was also used as a
support vehicle during the Space Shuttle Approach and Landing Tests at
Dryden in 1977, and for a variety of general purpose airborne simulation
studies related to general aviation aircraft.
