DARPA/ONR Tactically Exploited Reconnaissance Node (TERN) UAS

money and a new DARPA Director who had other priorities.
 
Wonder why nobody went back to the XF5U/V-173 "Flying Flapjack" design for this. While I don't think it could ever take off vertically, I'm pretty sure it could take off with ~30knots wind over the deck. Just time the takeoff for when the ship turns to put the wind about 30deg off the direction of motion. I know it could hang off the props for a vertical landing, or do a super STOL landing with maybe 50ft forward roll.

Single T700 or so class engine (~2500hp), Currie Industries 9" ring and pinion with 2.73:1 gear reduction to turn 6000rpm at the engine to 2200rpm at the drive shafts, H53 90deg tail rotor drive gearbox.

While this was indeed the aim, as far as I know, this was never demonstrated with the V-173, I assume due to lack of power, and of course, the XF5U prototype never flew . . .

cheers,
Robin.

I did not realize they had gotten that far with a prototype. To bad it did not get into the air.

From another discussion, Karem looks like it may be making progress on its ANCILLARY entry: There are FAA registrations for three aircraft under the designation TR-8 that could be their ANCILLAIARY design.

The entry for N362ZK says it has a 2-cycle engine. This aircraft clearly has turboprops.

The entry also says N362ZK is designated a TR-8. Based on the TR-36 and TR-53, Karem's naming convention for tiltrotors seems to be TR-[rotor diameter in feet]. If so, TR-8 is much smaller than this design.

ETA: Interestingly, there are three aircraft designated as Karem TR-8s, all registered on November 27, 2024. Serial 00001 is N362ZK, Serial 00002 is N102KA and Serial 00003 is N477DM. Do those codes suggest anything to anyone else?

My hunch is that the Karem TR-8 is their entry in the DARPA Ancillary project:
