What role do “new generation” engines play in Iran’s next satellite attempts?

Question

Accepted Answer

New Generation Engines Aim to Enhance Satellite Launch Capabilities

Iran's newly unveiled "new generation" of engines is designed to improve the success rate of satellite launches into space. These engines feature advancements such as lighter composite materials and a movable nozzle, which is intended to provide greater maneuverability beyond the Earth's atmosphere. The Raad-500 missile, equipped with Zoheir engines, and the Salman engines, both utilizing composite materials, represent this technological progression.
Lighter Materials Improve Performance

The Zoheir engines, used in the Raad-500 missile, are constructed from composite materials, making them lighter than previous models that used steel. This reduction in weight is a critical factor in rocket and missile design, as it can lead to improved efficiency, greater payload capacity, or the ability to achieve higher velocities with the same amount of fuel. Consequently, lighter engines contribute to a more effective overall launch system for placing satellites into orbit.
Movable Nozzle Enhances Maneuverability

The Salman engines, also made from composite materials, incorporate a "movable nozzle." This feature is specifically designed to aid in the delivery of satellites into space by allowing for "manoeuvrability beyond the atmosphere." Such maneuverability suggests an increased ability to control the trajectory and orientation of the spacecraft during its ascent, which can be crucial for achieving precise orbital insertion and overcoming atmospheric disturbances.
Technological Advancements for Future Missions

These "new generation" engines represent a step forward in Iran's indigenous aerospace capabilities. By developing engines with composite materials and movable nozzle technology, Iran is aiming to overcome previous launch challenges and enhance its capacity to successfully deploy satellites. While the specific impact on future satellite attempts is not detailed, the stated functionalities of these engines point towards a strategy of improving launch reliability and precision.
