Airplane First ever plane with no moving parts takes flight

The Guardian 21 November 2018
Quote:
The first ever "solid state" plane, with no moving parts in its propulsion system, has successfully flown for a distance of 60 metres, proving that heavier-than-air flight is possible without jets or propellers.

The flight represents a breakthrough in "ionic wind" technology, which uses a powerful electric field to generate charged nitrogen ions, which are then expelled from the back of the aircraft, generating thrust.
Video below.

"This video is unavailable." I suspect it will be a while before this is available commercially; not many people can fit on a plane that weighs less than 6 lbs.

Technically, a rocket has no moving parts, either. A pulse jet may have no moving parts depending on the design. A ramjet has very few moving parts, the only ones would be in the fuel delivery system. Admittedly none of those are very practical solutions for most types of planes.

My main question is what the energy efficiency of using an "ionic wind" engine is compared to a turboprop.

I was able to view it form the article. I wouldn't so much call it flight as I would "sustain a glide a little longer."

It's basically some flimsy glider that can be launched by hand or catapult (and needs to be in order to take off) and it's "flying" inside an enclosed building. It doesn't turn and, as I said, doesn't seem to be able to sustain itself--only keep from going down quite as fast as it otherwise would. I suppose during one (count it, one) of the takes, it's able to maintain altitude.

To be fair that would be a fairly accurate description of the Wrights brothers first flight as well. It will be up to engineers to see if efficiencies can or can not be improved to make something practical on larger scales.

I see lots of scope for an aircraft like this. I've spent a good chunk of my career dealing with unmanned aircraft, and this offers great potential opportunities.

- almost no moving parts means fewer parts to wear out causing failure or needing replacement

- lack of a propellor or jet means it is much more stealthier (reduced radar and noise signature)

- lightweight payloads can be used to provide lots of support to people on the ground (communications etc)

This prototype has me excited.

As well as what is listed, if this could be combined with solar technology, it could create a vehicle that would have very long, if not nearly indefinite, cruise capability. That could leave to some very interesting options for traffic and agriculture uses, just to name a couple that popped in my head.

See? Itís still a nascent technology, and already weíve got some military guy thinking how we can weaponize it. And yet (g)you expect me to believe that all this time going to hyperdrive would allow a ship to cut through a much much larger ship like butter and nobody ever thought of using unmanned/automated ships as missiles to take out an enemy fleet (or Death Star) until TLJ? Please.

Sorry, couldnít resist.

But it doesn't always work.

Remember in Rogue One, several ships collided with Vader's flagship when trying to go to hyperspace and bounced off.

New technology is always turned into military uses.

Or porn uses. Or military porn uses.

It could animate sky penises over the course of an entire day.

Any rocket more complex than a bottle rocket has moving parts. Fuel pumps and nozzle movement hardware at least. The biggest challenge to developing modern rockets for space flight wasn't developing the engine it was developing a steerable engine. Steering is required for all rocket flight. A rocket like the Saturn 5, at launch, is basically a pencil balancing on its point. Without a steerable engine all you get is a really big crater near the launch site.

Both pulse jets and ramjets have fuel pumps and valves.

The same thing goes for aircraft: the Wright Brothers didn't invent the first self-propelled heavier than air vehicle, they invented the first one with a steering system.

Reading

Could you elaborate on any prior examples that were able to stay airborne under power but lacked a steering system? I'm aware that others have claimed to be the first, I'm just not aware that any of their claims have been widely accepted (based on lack of evidence).

The Ader-…ole achieved a brief, effectively uncontrolled flight in 1890.
