DS-51-DIA HST® (93mm)


 

In 2011 we were the very first ones to launch an EDF of the 90mm class, build up on the low-speed HST Technology. The design of the new DS-51-DIA HST® implements all features of the bigger HST® fans:

>> a perfect match of fan and motor design

>> brand new motor design meets the high torque requirements of the 12 bladed rotor

>> highest efficiency of 64-70% (fan-motor-controller) notwithstanding the high torque conceptlong flying times plus high power input without damages or overheating

>> 12-bladed rotor for lower rpm and high flow deflection CFRP-Aluminium design with ultrathin rotorbladeshigh modulus carbon fibre shroud

>> perfect true running due to collet rotor mount3-phase wiring comfortably attached at the fan shroud Right now the fan is in its final intensive test phase

Additionally, we provide the following add-ons for your individual requirements: special bearing for longer durability, strengthened and abrasion-resistant blades for sandy fields, and for several HST types we offer special magnets for jet model flying in warmer regions.

DS-82-DIA HST® (120mm)


The established HST fans DS-94-DIA HST® and DS-77-DIA HST® have been reconsidered in order to achieve even more efficiency while keeping its cool operation level and high reliability:

>> improved aerodynamics at the stator for maximum thrust

>> high-temperature resistant adhesives allowing for reliability even in extreme environments

>> Rotor enhanced by means of an optimised carbon fibre roving ensuring highest crash resistance and reliability

>> slightly increased surface area for more take-off thrust

>> ribbed full aluminium stator providing cool motor operation at all times in combination with our patented cooling system

The new 120mm DS-82-DIA HST® still can be ordered with three different motor options. Motors haven been optimised magnetically and equipped with a stiff 10mm precision shaft. All rotating components are fine-balanced. The propulsion is build up from finest carbon/epoxy and aluminium parts. High modulus carbon fibre comes into use for the rotor blades and shell.

The DS-82-DIA HST® is a fan of the 128mm class which can be applied within a wide performance range and runs extremely cool due to its high efficiency level. That way we are in the position to guarantee long-lasting reliable operation of the fan in your high-quality jet model airplane!

DS-215-DIA HST® (195mm)

 

 

Our successful HST® fan series is now extended with a further extremely efficient and powerful ducted fan: the DS-DIA-215 HST®. This new class of 195mm electric fans achieves a static thrust of up to 250N at 15kW of power. During the development phase we were able to optimise the efficiency level, reliability, and its sound. Hence, we applied all of our established know-how from our HST series striving for best results.

By means of numerical simulation in combination with practical testing we could:

>> optimise the fan’s efficiency level (CFD)

>> optimise the motor’s efficiency (CEM)

>> ensure reliability of all components (FEA)

Our unique aluminium hollow shaft allows for a very high resonance point. Such mechanical feature allows the use of smallest tip clearances. The integrated motor in its new patented design propels the fan with powerful 10Nm of torque. Rotational speed was intentionally kept low at 14.000 U/min. The motor is cooled by means of our patented cooling system. A so-called fan containment made from high tech fibres manages to reduce the energy of debris to an absolute minimum and provides safe operation at any time. The DS-215-DIA HST® is the ideal propulsion for your single-engined jet model with a maximum weight of 25kg.
