With a fan swept area of 94cm² and a diameter of 120mm the DS-94-DIA HDT is currently our biggest and most powerful ducted fan. This fan can efficiently convert power inputs of up to 5.7KW into a very high thrust impulse - thus being an ideal alternative for turbines of the 80N-class.

Along with the design of its predecessor - the DS-94-DIA 3-ph - we developed the 8mm shaft system - by now an established and absolutely necessary size for handling the high motor powers in a 120mm fan unit. The optionally available Secure Fan Fix-system now also provides the possibility to precisely and securely fix the ducted fan within the fuselage.

Like all our ducted fans the DS-94-DIA HDT is also produced in CAD-CAM molds, hand-laminated and assembled in Paderborn. Since early 2009 all HDT-fan units are produced with ultra high modulus-CRP reinforced shrouts.

All ducted fans of the DS-XX-DIA HDT series come fully assembled, fine-balanced and quality-checked, you simply have to install your motor and the system is ready to fly. They are hand made in Germany and go through vigorous testing and inspection before shipping.
