*SMACKS FORHEAD*

F35 uses the lift fan for it's VTOL...YES it produces heat but look what they had to do
for the harrier..do you really think there afraid of repaving runways? Also Eglin has been
on the list for a new tarmack and runway for a few years now they had cracks in the main
runway had a friend who used to be based there.

"Whats the idea of being stealth"


Though they may be pathetic terrorists, they still have AA weapons like SA-7's and light
AA guns. It's also just a modern pissing contest among nations, like "Hey, look at me. I
can bomb your ass back to the stone age before you even figure out what's going on"

Even with all these high tech aircraft like the f22/f35... wat use is it going to make if its
only gonna be used to bomb insurgents with little or no Air defence? Whats the point
being stealth?
===========
Wat star light? nvr heard of such a thing

very cool man, SG is one of the strongest militarized nations in SEA. Sadly for my
country, this is just a dream.

RSAF...
Singapore army have military training, code 'Star light' ,do you know?

first off thanks for the photos your right the F15 is a big a$$ aircraft, even though i
live in England i see(or hear) the F15E's almost daily flying from RAF Lakenheath (its a
USAF base).

as for the F35, there are 3 main versions along with 2 nation specific versions(so far,
there will be more i am sure.)

F35A - CTOL - this is the 'normal' take off and landing version

F35B - STOVL - 'short take off vertical landing' this is the one with the lift fan for the
USMC as the royal navy have switched into the C model

F35C - CV - CV cat launch and wire/hook recovery folding bigger wings

F35I - proposed version for Israel

CF35 - proposed version for canada

now having said all of that someone said "I live out at Eglin AFB in Florida" now i am
pretty sure that is a USAF base so i would think the problem is not with the lift fan (not
in USAF use) but on the heat on take off from the jets in 'normal' take off mode which
being a reheating (afterburner) engine can be a tad hot!

***EDIT***

just seen the F16 with those side fuel tanks, its gone from being a very pretty plane to a
right minger.

if it is the 'normal' engine that is the problem then there maybe a soulition there is the
proposed '2nd engine' that the US congress wants to cancel maybe that would be cooler.

...But isnt most of the thrust supposed to come from the lift fan, and the main engine is
limited to idle/low power?

Yea.
I live out at Eglin AFB in Florida. They're re-paving the runways with an extra-heat
resistant tarmac thing because the engine of the F-35 is too hot. The local newspaper
ran an article on it last month because all the construction workers were whining about
something. The Navy is also re-doing the ship decks because of the same issue

"The design provides extra thrust in the vertical mode with a shaft-driven lift fan
produced by Rolls-Royce. This propulsion approach, which is patented by Dr. Paul Bevilaqua
of the Skunk Works, circumvents the hover problems associated with high-temperature and
high-velocity air by providing much of the downward thrust with cool air from the lift fan.

The Rolls Royce lift fan is driven by a drive shaft connected to the main engine. Doors
open above and below the vertical fan as it spins up. The rest of the vertical thrust is
provided by a three-bearing exhaust nozzle on the main engine and two roll posts on the
wings. The exhaust nozzle, provided by Rolls-Royce, is used for lift and yaw control and
can swivel 110 degrees downward from the horizontal. Thrust for the roll posts, used for
roll control, is supplied from the main engine's fan section. This thrust comes from
cooler air that normally bypasses the engine's turbine section. The lift-fan approach
removes energy from the hot turbine section of the main engine, which, in turn, lowers the
main engine's exhaust temperature, producing an even cooler footprint."

Melt the runway...?

Lol f35 yeah i just read about it. Honestly the EQ we have is enuf.
The new 5th gen ftrs are just too way esp. 1 f22 can but like 3-5 f16s i think?
