400KW? That’s enough for 200 houses! Methinks that’s just a bit on the high side. That’s 540 horsepower used JUST for electrical generation.

I’m shocked.

How many radars does the plane have?

That's a lot of power, but it is a single engine craft, with (I assume) a single generator.

I didn't work on them, but I think the F-14 had a pair of 90 KVA generators.

The Boeing 787 Dreamliner is an all electric jet. Instead of bleed air from the engines, electrical power is used to actuate the surfaces, and the brakes. What hydraulic power that is still required is generated with electric pumps.

The 787 has two engines, each with two 250 KVA generators. That’s a total of 1 MVA of power available. The APU has two 225 KVA generators.

Of course, that is overkill, designed so that the aircraft can safely fly on on generator of one engine.

Well, they are sorta thinkin’ that the VTOL airframe
could substitute a directed energy weapon for the
vertical lift fan. It would need a lot of power.

2 kW per house? My wife’s hair dryer sucks that alone. Try an average of 7 kW per house.

This is for a short duration power load, not average power. Control surfaces that are typically hydraulic are now electric. Should all of these control surface activate at once, combined with all of the other systems that can be operational, the power consumption would exceed the power generation capability of the generators.

I work on a system that normally draws less than 100 watts, but when active, can draw thousands of watts for a few hundred milliseconds.

How much power do you think the JSF should use?
