Abstract:

The ability to optimize the design of V/STOL aircraft and to predict their performance
requires a good understanding of the complex jet-induced phenomena associated with
these aircraft. Presently, experimental work is the main avenue followed to gain
an understanding of V/STOL flows.  Numerical simulation has many advantages not shared
by experimental tools.  It therefore can complement experimental efforts in gaining
a deep understanding of the complex flow phenomena associated with V/STOL flows.
 A procedure that accurately predicts V/STOL flows has been formulated and a code
has been developed that allows the simulation of these flows.  This procedure has
been tested by applying it to a two-dimensional problem.  A code has been developed
to calculate the flow field of a planar impinging jet. The ideas formulated and tested
in Phase I will be a basis for the Phase II effort toward developing a pilot code
that will allow the investigation of single or multiple jet impingement on the ground.
 Phase II will encompass both numerical and experimental investigations with the
aim of resolving some of the unanswered questions associated with V/STOL flow fields.
