Army Projects / Re: ARPA/Advanced Sensors hypervelocity gun SAWS
« Last post by jsport on Today at 09:56:14 am »
The SAWS had been developed by the TRW (Thompson Ramo Wooldridge) Corporation. The weapon is a modified M-3 gun with a change to a smooth barrel and automated for remote control firing. The ammunition is a modified  50 bmg case with  depleted uranium flechette .

WOW thank you Tony. Can't think of better time to reintroduce but no is listening.  :(

Postwar Aircraft Projects / Re: EV-2T Unknown Cargo Airplane Project ?

EV-2T wings and tail surfaces remind me of the PZL 15 Blogger jet-powered, biplane crop-duster.

PZL 15 also used spare engines from Yak-40 trijet and L-39 production runs.
PZL looked like unrelated airplane parts flying in loose formation.
Looks like something that a bored Russian bureaucrat - with piles of surplus airplane parts - would dream up!
Hah!
Hah!

PZL 15 proved uneconomical in service and was retired after only 175 were built.

We wonder which bureaucrat got a promotion during this project!
Hah!
Hah!

You are right Riggerrob.

Two new drawings,the first one is based on Rodrigo Avella Esav design and Northrop AX/AF-X proposal posted above by VTOLicious,my version of this concept is not perfect,but this was the best i could do;

PSA-167



the second is based on Rodrigo Avella multirole fighter,and is a concept of a multirole fighter, for the program of the 90īs created to replace the F-16,and later cancelled;

PSA-168

Quality is necessary, but the best is the enemy of good enough. The big trouble is that IMO the US had eight years of being told it didn't need to be (or possibly even shouldn't be) a worldwide blue-water force and is now paying the price.
The last 8 years saw more blue-water hulls ordered and construction begun than the previous 8. And everyone's favorite punching bag, LCS, comes from a lot further back than 8 years.

It seems to me that uncowled props/rotors in those positions would be a potential hazard, in ground handling terms.

From the video it seems as if the entrance and exit is only planned from the front, requiring some kind of gangway.

indeed, the first iteration of Uber vehicles will operate from 'vertiports', which allows you to take advantage of some ground support equipment. Obviously any door-to-door service, which could theoretically land on unprepared surfaces like someone's backyard, would require a different layout. You'd probably want to put the rotors above reach of passengers.

@mboeller: thanks for posting the presentation!
