The J58 had a single-shaft rotor design, with an 8.8:1 pressure ratio compressor, which incorporated a unique compressor bleed bypass at high Mach number. When opened, bypass valves bled air from the fourth stage, and six ducts routed it around the compressor rear stages, combustor, and turbine. • The J58 engine was developed in the late 1950s by Pratt Whitney Aircraft Division of United Aircraft Corp. to meet a U.S. Navy requirement. It was designed to operate at speeds of Mach 3+ and at altitudes of more than 80,000 feet. • The engines of the SR-71 were very unique and innovative, as they had to operate at extreme speeds and altitudes. The SR-71 was powered by two Pratt Whitney J58 engines, which were a combination of turbojet and ramjet engines. • The SR-71 Blackbird, a now-retired twin-engine reconnaissance aircraft, has an inlet design based on a cone-shaped body, or spike, that generates an oblique-angled, cone-shaped shock wave at the inlet's entrance and a normal shock wave—one rising at a right angle from the direction of air flow—just aft of the internal .. • How much thrust does a J58 have? • The J58 was a single-spool turbojet with an afterburner. It had a unique bleed from the compressor to the afterburner which gave increased thrust at high speeds. This feature caused it to be referred to as a turboramjet in some writings. It delivered 25,000 pound-force (110 kN) of thrust dry and 34,000 (150 kN) wet. • What is the rpm of the J58? • The J58 engine had a maximum engine rpm of 7800-8000 at full power. The exhaust velocity of the engines can't be determined exactly as it depends on the mass flow rate, air density, etc. But the exhaust velocity should always be more than or equal to the flight velocity. • #how it works #how things works #how its made • What is the maximum thrust of the J58? • Proposed version with 32,800 lbs. thrust with afterburner; Mach 4 capability.
