Electra Secures Additional Patents Protecting its Advanced Hybrid-Electric Architecture for Ultra Short Takeoff and Landing Aircraft

Elec­tra has been grant­ed a series of U.S. patents that pro­tect core com­po­nents of its hybrid-elec­tric propul­sion and flight con­trol archi­tec­ture, a sys­tem designed to enable Ultra Short take­off and land­ing oper­a­tions while main­tain­ing con­ven­tion­al air­craft per­for­mance and safe­ty mar­gins. 

In a press release issued yes­ter­day (Wednes­day), these patents cov­er crit­i­cal ele­ments nec­es­sary to deploy elec­tric blown lift prac­ti­cal­ly, advanc­ing the company’s pro­tec­tion of its nine-pas­sen­ger Ultra Short air­craft.  

Togeth­er, the patents safe­guard the con­trol log­ic, pow­er man­age­ment, and pilot inter­face sys­tems that define how Elec­tra inte­grates elec­tric propul­sion into a prac­ti­cal, FAA-cer­ti­fi­able hybrid-elec­tric plat­form.

They cov­er sys­tems and meth­ods for con­trol­ling the flight path of a blown lift air­craft (US Pat. #12384550), pilot guid­ance dis­play for that air­craft (U.S Pat. #12298151), and a bat­tery dis­con­nect sys­tem that improves main­te­nance, per­for­mance, and safe­ty (U.S Pat. #12489181). 

Chris Courtin, Direc­tor of Tech­nol­o­gy Devel­op­ment at Elec­tra, said: “Our patent port­fo­lio pro­tects our archi­tec­ture and the abil­i­ty to man­age pow­er, lift, and ener­gy safe­ty in a scal­able hybrid-elec­tric con­fig­u­ra­tion.

“Where tra­di­tion­al air­craft rely on aero­dy­nam­ic con­trol sur­faces, our dis­trib­uted propul­sion sys­tem makes the motors them­selves an active flight con­trol ele­ment. That improves pre­ci­sion, reduces work­load, and makes Ultra Short air­craft fly like any oth­er fixed wing air­craft.” 

Inte­grat­ing Pow­er and Con­trol 

The flight path con­trol patent describes a closed-loop sys­tem that enables pilots to com­mand the aircraft’s flight path angle through a sin­gle inte­grat­ed pow­er con­trol inter­face.

Instead of manip­u­lat­ing mul­ti­ple throt­tles or con­fig­u­ra­tion switch­es, the pilot sim­ply selects a mode—takeoff, cruise, descent, or reverse—and the onboard com­put­ing sys­tem dynam­i­cal­ly adjusts thrust across mul­ti­ple elec­tric propul­sion units to main­tain the desired flight path. 

This archi­tec­ture under­pins Electra’s blown-lift approach, in which dis­trib­uted elec­tric propul­sors mount­ed along the wing accel­er­ate air­flow to dra­mat­i­cal­ly increase lift at low speeds.

The algo­rithms and lookup tables con­tin­u­ous­ly opti­mize each propulsor’s thrust by ref­er­enc­ing real-time air data, air­craft atti­tude, and con­fig­u­ra­tion sen­sors. The result is fine­ly tuned, pow­er-based con­trol of lift and atti­tude, which is key to achiev­ing reli­able Ultra Short per­for­mance with­out com­pro­mis­ing effi­cien­cy at cruise. 

A Prac­ti­cal Path to Hybrid-Elec­tric Flight 

Elec­tra says its approach solves the range and infra­struc­ture lim­i­ta­tions that have hin­dered ful­ly elec­tric air­craft.  Its hybrid-elec­tric archi­tec­ture uses a tur­bo­gen­er­a­tor to sup­ply con­tin­u­ous pow­er to dis­trib­uted elec­tric propul­sors, enabling long-range, pay­load-capa­ble oper­a­tions with­out rely­ing on ground charg­ing infra­struc­ture. 

Electra’s sys­tem archi­tec­ture enables Ultra Short take­offs and land­ings in under 150 feet, uti­liz­ing exist­ing run­ways, park­ing lots, and soc­cer-sized fields. The com­bi­na­tion of dis­trib­uted elec­tric propul­sion and a hybrid-elec­tric pow­er­train deliv­ers heli­copter-like per­for­mance with the safe­ty, range, and cost effi­cien­cy of a fixed-wing air­craft.   

Courtin added: “These patents cap­ture how we make elec­tric propul­sion not just fea­si­ble, but prac­ti­cal in the real world. By sim­pli­fy­ing con­trol log­ic and embed­ding safe­ty at the sys­tem lev­el, we’re enabling com­mer­cial hybrid-elec­tric blown lift cer­ti­fi­ca­tion and deploy­ment, on a pro­pri­etary basis.” 

Next Stop: Cer­ti­fi­ca­tion 

Electra’s EL2 tech­nol­o­gy demon­stra­tor air­craft has already com­plet­ed suc­cess­ful flight test­ing using Electra’s pro­pri­etary hybrid-elec­tric propul­sion sys­tem. The com­pa­ny con­tin­ues to refine the inte­grat­ed con­trol soft­ware and pow­er man­age­ment log­ic as it advances toward com­mer­cial­iza­tion of its flag­ship, nine-pas­sen­ger EL9 Ultra Short air­craft.  

With the EL9, Elec­tra is pio­neer­ing Direct Avi­a­tion, a new mod­el of region­al air mobil­i­ty that saves trav­el­ers time, max­i­mizes exist­ing infra­struc­ture, and con­nects under­served com­mu­ni­ties.

The first test flights are planned for 2027, with cer­ti­fi­ca­tion and com­mer­cial ser­vice entry antic­i­pat­ed in late 2029, into 2030 under FAA Part 23 reg­u­la­tions.
