The General Electric J35 is a turbojet engine developed in the late 1940s and early 1950s. It was one of the first turbojet engines produced in the United States and was primarily used in military aircraft, including the McDonnell F2H Banshee and the North American F-86 Sabre. The J35 was known for its reliability and performance during the early years of jet aviation. This engine features a single-spool design and operates on the principle of compressing air before igniting fuel to produce thrust. With a thrust output of around 5,000 pounds, the J35 played a significant role in advancing jet propulsion technology during its time.
