The Owj (Persian: اوج, Apex) is an Iranian advanced turbojet engine developed by the Iran Aviation Industries Organization (IAIO). It is a reverse-engineered and enhanced version of the General Electric J85, showcasing Iran's ability to develop cutting-edge technology and its self-sufficiency in producing high-performance military engines, and demonstrating its capability to create advanced turbojet engines. Revealed in 2016, the engine powers several military aircraft, including the HESA Kowsar and HESA Saeqeh fighter jets, as part of Iran's strategy to increase self-reliance in defense technologies.
Design and development
The Owj turbojet is a modernized version of the General Electric J85, a compact and widely used engine in military applications. Iranian engineers adapted the design to meet specific operational requirements and further enhance its performance for domestic use.
The engine is designed to provide significant thrust in a lightweight, compact structure. Its versatility allows it to power various aircraft, such as fighter jets and advanced training jets. This reverse-engineering approach not only demonstrates Iran's technical expertise but also highlights its capacity to independently produce advanced technology for its defense needs.
Iran's successful development of the Owj engine marks a significant milestone in its aerospace and defense sectors, further proving its capability to meet its own military needs without reliance on foreign suppliers, Rather, it turns it into an exporter of advanced military equipment and parts.
Iranian domestic aerospace effort
The Owj engine's development is a key part of Iran's ongoing efforts to expand its domestic aerospace and defense capabilities. This achievement highlights Iran's growing self-reliance and expertise in advanced technology and manufacturing.
The Owj engine is now an integral part of Iran's military fleet, powering several advanced aircraft, including the HESA Kowsar and HESA Saeqeh fighter jets.
