YF-23 S-duct engine air intake with the porous suction panel in front. The YF-23 was statically unstable — having relaxed stability — and flown through fly-by-wire which provided artificial stability with the flight control surfaces controlled by a central management computer system.
The Northrop/McDonnell Douglas group promoted the larger YF-23." I might be wrong, but I don't think anything would be lost here by deleting the first sentence and going with: "Lockheed, Boeing and General Dynamics entered the YF-22, while Northrop and McDonnell Douglas promoted the larger YF-23."
The YF-22 and YF-23 in formation during flight testing in the early 1990s The squadron was first activated as the 6511th Test Squadron in March 1989 to conduct the Advanced Tactical Fighter program. It began flying the Northrop YF-23 on 27 August and the Lockheed YF-22 on 29 September 1990, flying both through December 1990, though the ...
The YF-23 is a liquid rocket vernier engine, burning N 2 O 4 and UDMH. [5] It is used in along the YF-22 to form the YF-24 and YF-25 propulsion modules. [ 3 ] [ 6 ] [ 7 ] [ 8 ]

The YF120 had different nozzle designs for the YF-22 and YF-23 technology demonstrator prototypes tailored to the specific airframe. The YF120 on the YF-22, registration number N22YF, was equipped with thrust vectoring nozzles. The engine for the YF-22 featured a two-dimensional thrust vectoring nozzle that could vector in the pitch direction ...
Virginia Tech students built a model aircraft with a Pelikan tail and got positive results for its viability using a wind tunnel. [4] The analysis by the students found several advantages such as a lower vertical surface area, which aids in stealth; less drag due to skin friction; and a lower weight due to the need for two as opposed to the usual four hydraulic actuators.
