The highest-altitude rocket ever launched by Pars Rocket Group, powered by our most powerful hybrid engine.
Developed using hybrid motor technology, the engine uses paraffin as solid fuel and N₂O as oxidizer. The burn duration is approximately 10 seconds, maximum thrust is around 3 kN, and the total impulse has been calculated at 18 kNs.
The nose cone is manufactured from fiberglass, with the first 50 mm made from aluminum; the nose cone features a Haack / Von Kármán profile. The rocket body is made of fiberglass and consists of two riveted sections, with a total length of 3.13 m. The fins are manufactured from carbon fiber, designed for structural integrity and weight optimization. The launch weight of the rocket is approximately 35 kg. The rocket is designed with a single pyrotechnic separation concept that activates at apogee (maximum altitude). The recovery plan involves the deployment of the recovery system at this altitude to ensure a safe descent.
The avionics system is designed to meet all operational requirements of a hybrid-propelled rocket, including ignition, communication, recovery, and flight tracking. The "Körfez" Avionics System operates with an STM32F407ZGT6 microcontroller. For data acquisition and orientation tracking, the system uses a BNO055 Inertial Measurement Unit (IMU) and a BMP585 high-precision pressure sensor. The system architecture blends modularity with compactness — core avionics components are embedded directly on the board, while LoRa, SD card, and GPS units are integrated as modular components. The communication infrastructure is reinforced with an RFM95 backup module alongside the primary RF module, ensuring continuous data transmission. The actuator layer supports a total of 5 actuator control channels: one servo motor driver, two separation lines, and two electronic igniters. Additionally, the system provides hardware support for tube pressure measurement. The avionics system is powered by a 12V 3S LiPo battery, with power stability maintained by two custom-designed buck converter voltage regulators providing 12V → 5V and 12V → 3.3V conversion.
