Northrop N-63

About the prototype

The Northrop N-63 was an unconventional VTOL turboprop tailsitter aircraft proposal submitted to the US Navy’s convoy fighter competition of 1950, which ultimately produced the Convair XFY-1 Pogo and Lockheed XFV-1 Salmon. It was a single-seat high performance fighter designed to protect convoy vessels from attack by enemy aircraft, and for vertical unassisted takeoff from, and landings on, small platform areas afloat or ashore. The N-63 featured a straight wing with pronounced dihedral and a very large ventral T-tail; armament consisted of four 20 mm cannon mounted in large pods on the wing tips. The aircraft was powered by an Allison XT-40-A-8 turboprop engine driving 15.5 ft six-blade dual-rotation propellers. The Northrop convoy fighter was designed to land vertically on a robust central landing strut in a collapsible tailcone as well as small shock absorbers located on the aft ends of the wing pods and vertical stabilizer; these landing support points were spread far apart to enhance stability on the deck. (from "Northrop N-63 Convoy Fighter: The Naval VTOL Turboprop Tailsitter Project of 1950" by Jared Zichek)

Controls

Flight controls as per standard.
AG1 - engine.
AG8 - gyroscope (it can be disabled, since takeoff can be performed without it; turning on the gyroscope is desirable to simplify the landing process)
LandingGear - switching to flight/landing mode.

Flight/landing mode

These processes are well illustrated in the following video: https://youtu.be/--0sYuheoPU?si=fty1rxJr_k9Rdp-0
As you can see, the take-off process for all tailsitters, which include Northrop N-63, does not pose any particular problems.
Difficulties begin during the landing process. To facilitate landing, I added a gyroscope to the design, which, when activated, will move the aircraft to an upright position. You will be required to reduce the engine power for a smooth descent and adjust the position of the aircraft using the rudders.

Armament

4x20-mm Aircraft Automatic Gun AN/M2
