vortex,

you’ll be in compression on the way up and on the way down, on the way down you’ll be in greater compression than on the way up, although if your pulling 4g vertical acceleration, you’ll be under plenty of compression……the compressive stress will significantly reduce the time taken for the cylinder to fail as heating the cylinder will cause the material of course to weaken, and, buckling stress being related to applied force, fail. therefore one could assume that, with linear compressive loading, a 4g acceleration will cause twice the compressive loading of a 2g acceleration, and hence fail in half the time.

this is of course a totally vertical cylinder only under compressive loading, if its inclined it will actually probably fail due to the secondary effects of the heating…..i.e. the heating and gravity will cause a mis-alignment of the cylinder and therefore a non-equal pressure differential around the cylinder, the result of which is movement, until the pressure differential is satisfied or until critical structural failure due to dynamic (air driven) loading conditions.

qinetiq have already trialled a runway debris detection radar, but the boy’s done good as they say!

or Fury?

and I’m not thinking about that sabre wannabe….

or swords……broadsword?

werent BAe, as was, involved with the first Northrop design which, when shut down was virtually supplanted to lockheed martin???

however AirtoAircombat is correct in stating that BAe has too much riding on jsf. considering BAe has bought up a shed load of us defence systems companies its in it for the long haul, and BAe Systems North America is BIIIIG!!

Matt, its planly obvious the uk will never develop a back bone for use agains the us…..i have to live with that fact…………it hurts………

you have the jsf (in the shape of the F35) because of the uk. look what the ‘all-american’ team came up with

……cue gopping pile of poo jsf-32……….

REPLICA, IMHO was aimed ENTIRELY at proving to the americans that we could do the same thing all on our own……..the americans-in-charge being the super-paranoids that they are let us in so that they could have the same but better airplanes that we have.

It has been categorically stated that NO-ONE gets to see the inside of a flying surface leading or trailing edge outside of the phantom works and maybe some usaf sites.

the brits should not pull out of this because of the money invested, but they should pull out because we need to re-develop a political backbone. Start by pulling out of the no-hoper iraqi situation.
