I have an engineering document that refers to "full military power"
in the context of a gas turbine. I can deduce that it is higher than
"normal power" but short of afterburners. Is there a formal definition,
maybe some specific percentage of "normal power"?

Thank you.

Full throttle without lighting the afterburners.

In heavies, there are often various levels of maximum power, defined
by how long one can run at that power. With the possible exception of
the B-1 (which has afterburners), no heavy that I know uses the term
"military power".

In fighters, on the other hand, there is one full throttle setting
short of engaging the 'blower - military power.

In the Navy, it is full thrust without afterburner, limited to 30
minutes. After that time, a reduced "normal" rated power setting must
be used. Military thrust is usually limited by RPM and EGT.

Strange that these terms still survive. While they may be RAF in origin
the earliest record I have for them is 1942 era USN Fighter Direction
Officer use. Then the terms were:

SAUNTER = cruise
LINER = unknown as to the exact meaning
BUSTER = Best sustainable speed
GATE = Maximum speed
ARROW = a true heading instead of magnetic.
EMERGENCY LIGHTS = instruction to activate a special feature of IFF to
make an IFF aircraft stand out in the crowd.
GUNS = warning to intercepting VF they are in range of TF's guns and to
break off chase.


John Monsarrat in ANGEL ON THE YARDARM mentions a number of the FDO terms
in context. As a FDO he had to know them all. Too bad he didn't include
them in an appendix.

Full military power is simply 100% throttle w/o using afterburners.

Usually, the throttle goes from 0 to 100 %, with a detent for
afterburner and a detent for reverse thrust (if so equipped)

Now, during WWII, they used WEP - War Emergency Power, which is a
higher than normal throttle setting (110% or something, if I recall)

This is how I understand them as well:

Gate - push past the gate into WEP

When I was Air Operations Watch Officer in USS Nimitz, I told pilots
to "buster" about two or three times a day. I only told one guy
*ever* to "gate, if possible." I think someone would have mentioned
it if I'd been mixing the terms up.

Jet engine thrust is controlled by a fuel controller. The throttle
has a switch at 80%, below which the afterburner can not be engaged.
The full thrust setting is done at engine trim. Pushing the throttle
past 100% does nothing.

Hmm. I remember reading this a long time ago. I'll defer to your better

The gate is a lockout for AB below 80% thrust. It is not posible to
engage the AB below that throttle setting. On some throttles there
are .020 lockwire holes at 80%. Full mil power refers to engine
thrust without AB. (ie 100% thrust)

I remember hearing news reports on CNN during the Gulf War where
pilots were thrilled to actually get to use thier AB.

Sorry if I am confusing things, but I am sure that 'Buster' and 'Gate'
have their origins in RAF 1940's r/t practices. (Wasn't there also
'Liner' for maximum endurance, or something like that?) So I think AB
is later usage that has developed, although operationally it may mean
the same thing (see below).

I know there are a few people out there with a slight down on Bill
Gunston at the moment, (but hey, if your output is vast, there are
bound to be a few mistakes, so give him a break), but the relevant
definition he gives for 'Gate' in Jane's Aerospace Dictionary is in
the form of a quotation:

5 In air intercept: ''Fly at maximum possible speed for limited
period'' (DoD)

He quotes 'Buster' as 'fly at maximum continuous power'.

The definitions are definitely in quotation marks, with one attributed
to the DoD. So does anyone know which DoD document is the source he
used for the definitions.

I get user unknown when I answer your email. I say you are full of
shit. Moving the throttle only changes an input to the fuel
controller. Overspeeding J-79s creates a catastrophgic failure in
short order.

Well, John, that depends on what Jet Engines you're talking about. The
4 J-79s on the B-58 developed full military power (100%) at full
throttle (without lifting). Then you lifted any or all of the throttles
and moved them further forward which lit the afterburners. We had about
3-4 inches of variable afterburner throttle settings unless the RAT got
to a certain level. Above a certain RAT (I can't remember) the RPM
range control was automatic. You could always achieve full overspeed
RPM by raising the throttles again and placing them in overspeed or,
with the throttles at full burner (but not in overspeed range), the
engine control automatically selected overspeed under certain RAT
temperature conditions.

I have a question for all of you who talk about FULL Military Power.

On the Recip engine there was no such thing as FULL Military Power. It
was listed in the engine power chart only as Military power.

Speaking of the Recip engine:
If you use the term Full why then isn't there a setting called partial
military power. There was only one setting for Military power. Other
setting were call - War Emergency / Take off Power / Military Power /
Climb Power / Cruise Power. Is the term FULL used when speaking of the
Jet engine. If so apparently this may be a term used for Jet engines
only, but it doesn't make a whole lot of sense.

Erik,

The only reasoning I can come up with for the jet engines is that there
are various setting based on exhaust gas temperatures for them. In the
A6 we had Max Continuous which was the power (limited by EGT) we could
run as long as we needed. Sometimes that was less than 100% rpm. As
long as we didn't exceed the maximum allowable EGT we could always run
100% for up to 30 mins.

FWIW

John, I was a pilot in the B-58 at Little Rock AFB from 1966 until we
scrapped them in 1970. I was an instructor in B-58 CCTS when we
scrapped them. By then they all had either the J79-GE-5A or J79-GE-5B
engines with nacelle mounted supersonic intake and articulating spikes.
It's been a long time but it seems the overspeed was to somewhere
between 102-106%. I have an appointment now but I'll ask other members
of the B-58 Ass'n if they have the exact data. In the meantime you can
get some info off my home page at http://home.pacbell.net/schmidt/

There you'll find a picture of the 58 and some good links for other
data on it and other military aircraft.

One of my relatives (I forget which one) was involved in the maintinance of
RR engines from spitfires in the second world war. He told me a couple of
years ago that once the throttle had been pushed through the gate (as it has
already been mentioned this was a thin piece of wire) the engine was removed
from the plane and stripped and checked over, once the plane had returned.
Generally the reason was when a pilot got into a sticky situation in a
dogfight and in trying to get out of it pushed the throttle through the gate.
He never mentioned anything about "buster" though, which leads me to think
that it wasn't a term used back then.

Well that was my $15 worth (sorry the exchange rate is crap at present)

Better not get too uppity when you don't know what you are talking
about. The J-79 and at least a few other jet engines I have flown
develop what is called "full military power" at 100% RPM but before the A/B
is lit. When you "go around the horn" or "lift the throttle" and enter
the afterburner range you put raw full into the area after the main engine
and , while you don't change the RPM, you get a significant increase in
power. In the CF-104 for example, you went from about 10000 lbs of thrust
to about 15800 lbs. In addition to controlling the extra fuel this
movement also controlled the nozzles at the aft end of the tailpipe.

Check it out, before you lash out.

In USAF jet ops
SAUNTER = max endurance power setting (loitering)
LINER = normal cruise, max range power setting
BUSTER = max power without afterburner
GATE = max power with afterburner

The difference of power versus speed is significant. For
instance on a scramble they would specify "climb gate"
if they (GCI) wanted it. That did not mean max speed.
With SAGE radar sites, their computer would have
projected results with various options selected. a/c
performance was programmed and computer would
command military power (buster) climb unless it
figured it needed a gate climb to make the intercept
where/when they wanted.

I think I once encountered a GCI controller who read the
Navy definition of GATE = max speed rather than max engine
power and didn't think any farther.

Flying out of Pinecastle AFB, Orlando, Florida on a rocket
firing mission out west over Gulf of Mexico. While being
vectored for another pass I told controller I was running short
on fuel and had to break it off. I requested vector for
"home plate" (home base). Went something like:

Cont.: "Roger, turn starboard to 040 go GATE!".
Me: Negative GATE, I'm low on fuel.
Cont. I know. I'm trying to get you home fast.
Me: I won't make it if I go GATE. Wastes fuel.
Normal cruise will do nicely and get me home safely.
Cont.: Roger

This was covered more thoriughly in debriefing.

Trotti in 'Phantom over Vietnam' describes how the F-4<mumble>
would be set to min burner to clean up the smoky exhaust trials to
procede over target but I can`t remember whether this was at
military power or not.

I have retrieved the book from the #2 bookcase at last but now

Min burner is precisely that. It's the throttle position just ahead of the
full mil power position, into the AB range but at the most rearward portion
of it. On the F-4 throttles, once you reach full mil power the throttles
appear to be at a forward stop. You move the throttles outboard slightly,
then you can advance them further forward into afterburner. There were
only, as I recall, 4 stages of afterburner on the J-79 engine, so it wasn't
exactly "throttleable"; you would feel a distinct kick as each stage was
added. Said another way, within the AB range you could move the throttles
some distance and achieve no change in thrust, then suddenly the next stage
would be added.

Newer engines are more smooth between stages. The F-22 will be fully
"throttleable" throughout the AB range. This will be really nice for heavy
weight refueling, but then it achieves so much of its total thrust in mil
that AB might never be necessary for refueling.

A fellow Mt. Home recce WSO who came out of B-58s (DSO)at Bunker Hill in
late '69 told me (B-58 guys feel free to jump in here) that, at the
precontact position, his AC would pull One and Four back to idle and
modulate the inboards in min burner throughout the refueling.

A very broad and incorrect statement. Don't know who the
"we" is but it doesn't include thousands of present and
former USAF jet fighter pilots for last 50 or so years.

Maybe you should just say you are one person who hasn't
heard or used the term.

Having considerable experience flying several different
jet fighters over the years in USAF I can tell you "full military",
"full military power", etc was part of their vocabulary and used
routinely. Anyone having to communicate with them also was
familiar with the term. I'm thinking of other operational personnel
to include factory reps and engineers.

I don't know origin but I'd guess it was related to "full throttle"
equals "military" power early on in jets. 'Full Military' can give
a better sense of what's to be/being done.

I'm sure there are terms used in different types (cargo,
helicopter, transport, bomber, etc) USAF/USN/USMC/USCG
as well as foreign a/c that you may not be familiar with. Even
between USAF Commands/Wings/Groups/Squadrons terms vary.

I quote from T.O. F-106A-,1 30 Apr 1985, page1-42, 1-43

"After the button has been depressed, the audible warning
system is not reactivated until the throttle is advanced to the
FULL MIL POWER position, approximately 220 KCAS is...."

I guess you could, Phil, but generally we refueled out of burner. At max gross
weight refuelings (166,000#),we DID become power limited. But you always made
sure you advised the tanker's boom operator prior to lighting an afterburner.
Especially at night. Or the boomer might see the flame coming out of the engine,
think it was an engine fire and call a BREAKAWAY!

The way I was taught and found it easiest to do was to wait until I was
approaching an outer limit and then put one inboard throttle into afterburner and
quickly retarding the other 3 slightly to maintain position. Then you could work
with just the 3 not in burner to "fly the boom". One throttle in afterburner
always provided me with enough power to manuever, even at max gross weights.

Then when you finished refueling and broke off left or right to accelerate, if
you wanted to show off you could light all 4 burners to leave the tanker in the
dust. (But you throttled back out of burner before you went transonic.) You
didn't just "go" supersonic in the B-58. The CG envelopes supersonic vs subsonic
just barely overlapped. You'd set the CG to near the aft limit subsonic so that
when you went super you were near the forward supersonic limit and could then
move your CG further aft. A balance fuel tank in the tail was available to move
fuel to/from to change CG. Each 1,000# of fuel moved the CG about 1%. The fuel
panel had a CG gage that you could set an adjustable pointer on, switch to Auto
CG and it would automatically move fuel to give you the requested CG.

Yes now I recall. Trotti describes how the excess speed was
scrubbed off the the speed brakes in order to maintain desired
speed over the target.

Hi everybody,

Can anyone point me to a site where I can find high resolution images
of various fighter aircrafts (f-15, f-14, f-16, etc..). I need side,
top, bottom, front, back views preferably for a 3d animation project.
Thanks a lot.

Rodrigo

Check out the Information Now! site at http://people.delphi.com/todd3205.
The guy sells military photos on CD for scale modelers. Or e-mail him at
todd...@delphi.com. He might have what you need.

Also correct depends on type and believe it or not branch of service. A lot of different terms that describe similar events.
