Dufour Aero­space announced this week that Ger­man elec­tric propul­sion sys­tem man­u­fac­tur­er, Plet­ten­berg, has been cho­sen as a sup­pli­er for the tail thruster propul­sion unit of the uncrewed tilt-wing air­craft Aero2, reports a press release.

Simon Ben­drey, Head of Design for Dufour Aero­space, com­ment­ed, “Plet­ten­berg offer a com­pact, high torque, elec­tric motor which is per­fect for the tail pro­peller on Aero 2. Cou­pling this with a light­weight and ther­mal­ly effi­cient elec­tron­ic speed con­troller (ESC) which fits nice­ly with the air­craft, Plet­ten­berg has mod­i­fied the motor unit to pro­vide the sys­tem redun­dan­cy required for the con­tin­ued safe flight of the air­craft.”

Bas­t­ian Grein­er, CEO and Man­ag­ing Part­ner of Plet­ten­berg, added, “With our triple-redun­dant NOVA 15 LW motor, includ­ing three ESCs, with no sin­gle point of fail­ure, we sig­nif­i­cant­ly improve the Aero2’s safe­ty. The motor has been tai­lored for Dufour Aero­space and sets a new stan­dard in the trade-off between per­for­mance ver­sus robust­ness ver­sus weight.”


Ger­man-based Plet­ten­berg is a lead­ing devel­op­er and man­u­fac­tur­er of tai­lored elec­tric propul­sion sys­tems for the UAS mar­ket. The company’s mis­sion is to build the most rugged, but also light­est propul­sion sys­tems on the mar­ket. 

As part of a cus­tomi­sa­tion, Brush­less DC Motors (BLDC) such as the NOVA 15 LW, will be tai­lored for the cus­tomer. The motor is then com­bined with an ESC as well as the pro­peller, to deliv­er a sys­tem solu­tion which match­es the cus­tomers’ require­ments. 

Next to propul­sion sys­tems, Plet­ten­berg also pro­vides starter-gen­er­a­tor solu­tions as well as mis­sion-crit­i­cal acces­sories.
