This has me thinking of arrays of small for VTOL.

I wonder if just sealing the elliptical cylinder ends and depending on post-thrust reverse flow through the exit slot (and maybe simple flapper valves in the end caps) would suffice to get enough air into the chamber between pulses.

A similar-to-PETA entrainment of flow by rectangular "venturis" would also boost thrust from the EAPE array.

(EDIT - Fixed link to prior post. Not working right after recent T-P site upgrade.)

Laser-triggered electrical arcs:

(Edit) XX- -XX (Edit)
(Edit -- Gone behind a paywall. Bummer. One of the pictures showed a very straight, laser-triggered HV discharge over an EAPE-relevant distance when the laser was focused near mid-gap.)



Electrical arcs in reverse-flow vortices (bottom of page):
(Edit) XX- -XX (Edit)

(Edit -- Fixed dead link.)

Apparently, high voltage discharges can produce hard x-rays, and in some cases, gamma rays.

Some new research from Japan about suppressing hard x-rays by quenching "runaway" electrons with laser pulses:

The green rubs off. It's just a ploy to get more free money from the galactic government.
