while less than a month ago images of an strange engine published in internet that depicted Iranian supreme leader ayatollah ali khamenei and sorena sattari, science and technology deputy of president among other officials and scientists inspecting it and new achievements of country's aerospace sector. almost one week ago Iranian news outlets announced that a science based company successfully built country's first ramjet engine and today finally details of the engine released. RJ-HP1, Iranian first ramjet engine: Length: 956.5 mm Diameter: 360 mm Ramjet weight: 53 kg weight (Engine accessories): 25 kg Materials: Super alloys, steel Fuel: JP-4 Speed: Mach 2 Speed at low altitude and , Mach 2.7 at high altitude, Flight altitude: <1000M when in cruising stage Exhaust temp.: 2000K Thrust: 13 kN (~2900 lbf) after mass production of RJ-HP1, Iran can potentially use this engine to improve it's anti ship cruise missile inventory with supersonic missiles. (ramjet powered yakhont/oniks anti ship missile) also the engine can power anti aircraft systems with relatively slower but very long range missiles like UK sea dart and US RIM-8 talos. British sea dart (up) and US RIM-8 (down) also in the past US and other countries made very fast and high altitude flying reconnaissances drones with such engines. US D-21 drone on the ground and attached to the mother plane all these examples shows that the new engine Iran just revealed can boost it's defense industry to next level and enable it to pose bigger threat to it's enemies.
