“ELECTRIC AVIATION PING!.”

I wonder if they plan on making Russia and China do the same, or are they just looking for us to get our asses kicked by them?

Anyway, hybrids are fine for cars and are now even more reliable than gas cars (mainly due to the extreme pollution controls needed for gas-only vehicles). And they do GREAT regarding efficiency, due to being able to recover energy that was lost to braking in stop-and-go driving, and the effect of added weight of the hybrid components are relatively small, since it doesn’t have to supported in the air.

BUT, airplanes don’t do as well in stop-and-go flying, so it’s hard to see what benefits will be derived here, other than placating the Extremists who now control our government.

The only thing I could think of is stealth enhancement, silent, no heat signature..........................

"you do realize electric motors still get hot"

You obviously don't realize how piddling "hot" electric motors are compared to jet engines. The burning fuel in the combustion can of a jet engine gets as hot as 3600°F, and the exhaust gas at the engine exit (which is completely visible in ordinary a/c) can be 1000°F.

Show me your electric motor that can match those numbers.

Regardless, the temperature of the engine itself is irrelevant compared to the heat of its exhaust gasses because the a/c's skin can be shielded from the engine's heat, but there's no getting around the fact that at some point you've got dump the jet engine's 1000° exhaust overboard.

And that's a dramatically bigger ask than disguising anything coming off an electric motor.

The XRQ-73's only "visible" sources of heat will be the air getting heated as it passes through the ducted propulsion fans, and the heating of the a/c's skin from aerodynamic drag.

If it is Boeing it will be not be going...

Anywhere.

This is bribes creating corporate welfare.

IT'S A HYBRID!!!!!!!!!!!!!!!!!

It charges its battery using a jet engine-based APU, switches to pure electric for the stealthiest part of the mission, then APU back on for the return trip home.

The drone must be manufactured by Luckup!

Yes, that makes sense, avoid IR emissions during stealthy phase of flight. Disclosure: I haven’t read The Debrief or The War Zone articles yet.

When you do, you'll find that this is a tiny aircraft, total weight with mission equipment estimated to be 1,270 lbs., which makes this much more doable on a small scale.

Bypass flow and lateral diffusion can cool the exhaust substantially but certainly not comparable to the reduction from just shutting down the turbine!
