FORM 9B - PROJECT SUMMARY

PROPOSAL NUMBER 00-1 07.02-8546 (Chron: 001455 )
PROJECT TITLE
A COMPREHENSIVE ANALYSIS TOOL FOR DUCTED PROPELLERS

TECHNICAL ABSTRACT (LIMIT 200 WORDS)
The use of ducted propellers as the quiet propulsive device for Unmanned
Aerial Vehicles (UAV) is steadily gaining popularity. Their successful
application as the fenestron tail rotor is global and well established.
This research proposes a comprehensive analysis tool for ducted propellers.

In Phase I, an axially symmetric Navier-Stokes flow solver capable of
analyzing the ducted fan in climb, hover and descent will be developed
and integrated with an intutive graphical user interface. The rotor will be
modeled as an axis-symmetric momentum source in the governing equations.
An automated grid generation based on the geomtric characteristics of the
duct will be an integral part of the tool. In Phase II, the analysis tool
will be extended to non-axial forward flight conditions.

POTENTIAL COMMERCIAL APPLICATIONS
The software developed under this initiative will find wide usage in the
U.S. helicopter industries and aerospace industries in addition to the
US government. With the success of the software in predicting the
aerodynamics of ducted propellers, extention to dynamics, control and
accoustics will be considered in future initiatives.

In Phase III, the comprehensive aerodynamic analysis tool will be
wrapped with pre and post-processing capabilities and licensed to the industry.
