“Hartzell Gains FAA Type Certificate For First Part 35 Electric Engine Propeller, Designed & Tested with BETA Technologies” 

Hartzell Pro­peller has received FAA Part 35 Type Cer­ti­fi­ca­tion for the first pro­peller designed specif­i­cal­ly for advanced air mobil­i­ty (AAM) air­craft, reports a press release.

The release explains, “The com­pa­ny worked with aero­space com­pa­ny BETA Tech­nolo­gies to achieve this land­mark, con­duct­ing all test­ing of its pro­peller on BETA’s pro­pri­etary elec­tric propul­sion sys­tems (elec­tric engines), which are designed and man­u­fac­tured in-house by BETA.”

It con­tin­ues, “With this cer­ti­fi­ca­tion, Hartzell’s pro­peller is the first to earn FAA type cer­ti­fi­ca­tion specif­i­cal­ly for inte­gra­tion with elec­tric propul­sion sys­tems. These sys­tems, like BETA’s, are capa­ble of man­ag­ing a wide range of dif­fer­ent loads and con­di­tions — from regen­er­a­tive brak­ing to start­up — all of which Hartzell’s pro­pellers are unique­ly designed to sup­port. The approval comes after thou­sands of hours of ground and flight test­ing over four years, and ver­i­fies that the pro­peller exceeds the rig­or­ous per­for­mance and safe­ty stan­dards of FAA Part 35.” 

JJ Frigge, Pres­i­dent of Hartzell, com­ment­ed, “Our design specif­i­cal­ly for BETA Tech­nolo­gies is a five blad­ed, car­bon fibre, ground adjustable fixed pitch pro­peller that will have future appli­ca­tions for the entire AAM indus­try.” 

Kyle Clark, Founder and CEO of BETA Tech­nolo­gies, added, “Their (Hartzell) engi­neer­ing pre­ci­sion and deep cer­ti­fi­ca­tion expe­ri­ence has assist­ed us as we bring this air­craft to mar­ket and walk through our own cer­ti­fi­ca­tion steps.”

The two com­pa­nies have worked on the pro­peller devel­op­ment since 2021, from ini­tial aero­dy­nam­ic mod­el­ling and design to full-scale test­ing and val­i­da­tion. The result is a high-per­for­mance, low-noise pro­peller tai­lored specif­i­cal­ly for elec­tric engines and the next gen­er­a­tion of avi­a­tion. 

BETA will use Hartzell’s pro­peller to opti­mise the per­for­mance and safe­ty pro­file of both its ALIA VTOL and ALIA CTOL air­craft. The pro­peller is also built to serve all AAM air­craft that utilise sim­i­lar elec­tric propul­sion sys­tems. 

Back­ground

Hartzell Pro­peller is a Sig­nia Aero­space com­pa­ny and a leader in advanced air­craft pro­peller design and man­u­fac­tur­ing. It offers more than a cen­tu­ry of inno­v­a­tive expe­ri­ence.

The com­pa­ny is based in Piqua, Ohio.
