What aircraft is this?

I think it's a SP-2H by the looks of it

VP-18 circa 1962



There were several of those at Greybull

P2-V as evidenced by the Kerosene burners attached to the wings to help the radials.

One of the first warbirds I ever saw...

What's a kerosene burner? MikeD mentioned they where what they called the engines on the B-52's, but those are props on that plane.
Is it the same jet engine powering a turbo-prop? or are those extra jet engines?

I got into aviation late in life, so I am not steeped in the lore like a lot of you guys.

thx in advance

Early P-2s only had two recip engines. The P-2Vs had the addition of two J34 jet engines under the wings outboard the recips, as you can see in the photo with the Vee-shaped "Danger Jet Intake" signs that can barely be seen. Used primarily for takeoff or whenever additional power is anticipated to be needed. They didn't normally operate all the time.

Thanks MikeD.

So, to be clear, these where additional and independent (small) jet engines in addition to the (avgas?) piston driven engines. They where not an "external supercharger" that could be invoked on the normal engines and boost their power.

Do I have that right?

thx again!
 
Also, why the plexi-glass nose cone? Every time I see a plexi-glass appendage, I think machine guns, but no machine guns there.

Search and rescue? eyes on the water?

Separate engines yes. Westinghouse J34s. Ran on AVGAS, the high octane stuff such as the 115/145 Purple, 100/130 green, or 100LL Blue.

The main mission of the plane was Antisubmarine Warfare. So yes, eyes on water and for search and rescue.

That is the first time I have heard of purple avgas.

Yup. In addition to the above, there was 80/87 Red, and 91/98 Brown Avgas all at one time. I still remember fueling with them back in the day.

One of the 172's I learned how to fly in burned 80/87 red. The FBO was fanatical about renters knowing what fuel went in what plane.

Fascinating.

During my ppl training it was mix Red and Blue and you get Straw(?) no mention of the others.
 
The colors are made to go clear if the fuels are mixed. The straw would be JetA and has more of an oilly feel and evaporates more quickly than avgas

You can do the "paper test" if you have straw colored fuel to see if it's avgas or jet-a. Take a white sheet of paper and pour the gas on it. Avgas will evaporate and leave it pretty much the way it was. Jet-A will leave it feeling oily and the paper will be discolored.
 
Just a little more info on the picture. Its a P2V-7 from FAW-11/ VP-18 and you're right, its part of the Cuban naval blockade. Ironically, at the time the squadron was deployed to Naval Base Guantanamo. VP-18 was also used in the space capsule recovery during the early space program. The P2V-7 is just a little different, it has a canopy that's a bit higher and a bit wider and rounded as well as using the smaller tip tanks/radar/light pod from the P2V-5. It was re-designated as a SP-2H in 1962. The Navy also used the P2V-7 to experiment with using skis for landing in the arctic, they only did it a couple of times and had a failure with one of the skis coming partly loose from its mounts and had to do a gear up landing which ended the program.

We were getting jet fuel that came off barges at work, and that stuff was really straw colored. Then we switched providers and it was crystal clear. It looked like we were sumping spring water from the trucks.

Jet most definitely doesn't evaporate faster than 100LL. Jet fuel hangs around.

I can spill an entire bucket of 100LL on me and it will be gone and dry after a couple minutes time. Jet fuel? Stays with me all day long.
