C-130 rocket assisted takeoff length

Hi all.
Does anyone know C-130 rocket assisted takeoff length?

Is it possible that it can be 30 meters (100 ft)?


Thanks.

Hi all.

I think normal JATO take off distance would be in the range of 800-1000 ft.
depending on load.

Is it possible that it can be 30 meters (100 ft)?

The CREDIBLE SPORT aircraft modifed for a second Iranian hostage rescue
attempt were supposed to take off with about a 100-ft ground roll. They
used a massive amount of rocket assist, far more that the usual RATO units.

A couple of descriptions of Credible Sport:

Credible Sport actually got airborne in much less than 100ft. More like 2
1/2 - 5 tire revolutions.

The SAC for the Navy C-130G (equivalent to the C-130E IIRR)
is online. Normal vs. Jato (8 x 1,000 lb. thrust ATO
rockets) t/o runs (in feet) at weights of 155,000 (normal
max., 2.5g) and 175,000 lb (overload, 2.25g):

Calm, ISA @ SL, Military rated power and 50% flaps. 155,000
lb: 4,125/3,565 feet. 175,000 lb: 5,390/4,750 feet.

The C-130H values should be somewhat less, as it had more
powerful engines but the same max. weights. I don't know
how the C-130J stacks up for t/o.

The 130J isn't set up for Jato. Those Dowty props and RR engines really toss
it in the air without it though!

I can't speak of the distance that a Jato C-130D took since it was on snow
(skibird) but you tried to bounce the nose into the air at about 60kts.
When the ski cleared, it emmediately popped to about 90kts and you popped
the 8 jato bottles and were airborne and going up. That is got to be the
hairiest ride ever.

Not with a loaded Herc, and the standard JATO setup.

From the Standard Aircraft Characteristics Chart for the U.S. Navy
C-130G (The same thing as a USAF C-130E, but the Navy wouldn't use the
same subtype letter, would they? )

The normal JATO fit are 8 1000-KS-14 JATO bottles, which give you
1000# thrust for 14 seconds.

Takeoff ground run, no wind, Standard Day Sea Level at 155,000# weight
(Max payload)
4125' without JATO, 3565' with HATO
Distance to clear a 50' obstacle:
5810' without JATO, 4812' with JATO.

Note that the extra thrust doesn't help the ground run very much, but
does help the initial climbout quite a bit.

Peter, what did they do to the Herc that they flew off of the
Forrestal(?) ? (without JATO at that!)

Well, it does help with ground run if you can guarantee a 30 kt
wind down the runway every time...

That's true isn't it?...one tends to forget that ~30 knots is a
LOT of airspeed gain, especially at the top of the take-off roll
range, takes a comparatevly long time to gather that extra speed.

An a/c that you normally rotate at 105 you now rotate at 75
(well, not really but you get my drift)
