Since a P2V has both piston and jet engines.
You can see the doors that closed when the jet were not running. An earlier version of the P2V, named The Truculent Turtle, made a 55-hour 11,000 mile flight in 1946 from Perth, Australia to Columbus, Ohio.
OldNFO, do you know how those doors worked?

I Remember seeing P2V's from Glenview NAS (north of Chicago) back in the mid 60's. they would shoot apporaches at MKE. 2 turning and 2 burning. The doors on the jets did confuse me they must open them before starting.
I don’t know how the doors worked, either.
Nice looking aircraft, assuming an ASW package?

The doors appear to have a vertical "piano" hinge. I don't think they are spring-loaded, since they must be able to close in-flight.

They were mounted as a hinge in the middle so when open they form
an aerodynamic vane and when closed with a sizzlers jack to
push the trailing edges of the vane into the cowling.
Pretty clever arrangement.
Eck!
They were hydraulically operated, and as Eck said, closed off the engine completely to prevent salt water/FOD/bird ingestion. With the doors open and no fuel, they would rotate at about 10% RPM, and burned leaded gas, same as the radial. The fuel flow went up astronomically when they ran though... Something over 1000gph from what little I remember, and lead buildup on the stators. They were also 'idled' for landing, if an immediate go around was needed, depending on landing weight. And that is a sweet bird! I've seen her when I was down in Australia, and got to prowl through her, but not fly on her.
Same jets as the B-36 and C-123?
P2V used Westinghouse J34s, B-36 used GE J47s.
The J47 was almost twice as long as the J34, 195” vs 112”.
0_0 is correct, they were the 'little' jet engines!
