Why a Duct?

Why a Duct?



In 2007, we tested a 54" diameter, shrouded prop against a 76"free prop at the university of Maryland's Glenn L. Martin Wind Tunnel.

The results of that test confirmed that the smaller, shrouded prop produced more thrust than the conventional free prop at airspeeds up to 200 knots.

Welcome to Trek Aerospace


Trek Aerospace is the industry leader in shrouded propeller (“ducted fan”) technology.  Founded in 1996, Trek has been dedicated to understanding and improving shrouded propeller performance and efficiency.


Design Consulting 

We developed Trek’s proprietary CFD (Computational Fluid Dynamics) software program, TASPA™ (Trek Aerospace Shrouded Propeller Analysis), to design optimal shrouded propeller modules.  Testing in NASA and university wind tunnels has validated the accuracy of our code.  Flight testing of both manned and unmanned vehicles has further verified the real-world applications of our technology.  Trek’s knowledge base allows us to design and build shrouded propellers that produce 50-75% more static thrust than our nearest competitor.  Furthermore, our shrouded propellers outperform similar free propellers to airspeeds in excess of 200 knots.



We have the experience to design lightweight, yet strong, ducts and props; and we have the vendors lined up to fabricate our designs. Thousands of hours have gone into testing the ducts on our Exoskeleton Flying Vehicle, as well as our smaller UAV, we've even used our ducted fan technology for a category x watercraft!

We would be happy to help you design the ducted fan vehicle of your dreams.


Technology Licensing 

Trek has teamed and consulted on numerous other programs and projects involving shrouded propellers and/or autonomous control systems. We can work either on a contract basis or on a royalty basis, based on your project requirements.
