Re: Richard Branson reveals prototype for supersonic passenger aircraft

Look no further than the XB-70 Valkyrie for a similarly odd arrangement with two inlets serving 6 engines. It's just feeding a certain amount of air to an intake plenum for an arbitrary number of engines. It likely reduces complexity for the overall design.

Re: Why board from just one door?

Happens in the carribean quite often. They use two sets of stairs on the longer narrow bodies and split the crowd based on a row number.

Re: Richard Branson reveals prototype for supersonic passenger aircraft

My point with my suggestion of two complete, commercial turbofan embedded in the body and true ram jets on wing pylons or at least conformal underbody housings, is to avoid a whole host of problems and address efficiency and enissions. The turbofan are used for a quiet, emissions compliant takeoff a...

Re: Richard Branson reveals prototype for supersonic passenger aircraft

This isn't credible until they announce an engine partner that has a firm contract to develop and prode enough engines (and spares) for the test frames as well as the first production frames. The Lehman article on this is quite accurate from what I know of the biz. Military jets aren't designed for ...

Re: MadMax vs MOM: Now A Third Proposal, a simple stretch

I hope that people don't think that a wing root extension is going to be a simple thing. It affects engine placement and the associated wing structure. If you just keep the engines where they are and add a longer wing root, you effectively spread them farther apart. They will also be more powerful. ...

Re: 2 Usmc Heli's Collide Near Hawaii, 12 Feared Dead

They didn't have sufficient basic training in night ops to do COMBINED night ops. You have to have proficiency with the craft, then proficiency with the gear, THEN you can practice team proficiency. I'm vastly oversimplifying this all of course, but that's the gist of it.

Re: MadMax vs MOM: Now A Third Proposal, a simple stretch

I've often wondered what a melding of the 737 DNA with the dc-9 DNA would look and work like. I absolutely realize that you'd have to basically rebuild the thing from the ground up, but it would allow short, light gear, a low fuselage that makes ground services easier while making the structure heav...

Re: The MSY Thread - Part 5

I think that the plans for the third concourse need to include making the whole thing sterile for international arrivals with bypass for domestic overflow. FIS is really crammed in there, and only two international gates will make ground handling a challenge during charter season and restrict MSY's ...

Re: Remnants of old terminals

The original airport in New Orleans, NOL "Lakefront" has its original 30's WPA Art Deco terminal. In the 60s, it was given a "modern concrete shell" over the original structure and also made resistant to nearby nuclear detonations. Heavily damaged by Katrina, the "shell"...

Re: Iran unveil indigenous turbojet engine

Just a quick note, if you were going to pick an engine to copy/reverse engineer, the one in the F-5 would definitely be the one to shoot for first. It is a relatively simple, very reliable engine. It has a major advantage for less capable regimes, it doesn't use extremely exotic alloys internally. W...

Re: WN Engine Damage/Cowl Separation In Flight MSY-MCO

It's an Elon Musk / SpaceX term. He uses it to describe the process by which a rocket annihilates itself when it hits the ground with excess velocity, or an uncontained rapid burn of combustible material leads to an over-pressure situation inside of a space craft (it blows up). While I like the spec...

Re: WN Engine Damage/Cowl Separation In Flight MSY-MCO

Hello all! First time poster, long time lurker. Information from a few other sources indicates the following: 2 other pilots have stated that they had to use anti-ice around the same time as this flight while leaving MSY. A mechanic has reported that the cowl inlet anti ice system uses bleed air for...
