Solid Propellant Engine and General Information
ATA is the fourth solid-propellant rocket developed by Pars Rocket Group. It uses an HP 98/7680 engine and has a total impulse of 8307.79 N.s.
The engine burns for 4.43 seconds and produces 2434 N of instantaneous thrust. The maximum speed is calculated as 0.82 Mach, and the rocket is designed to reach an altitude of 10,000 feet.
Mechanical Features
The rocket body is made of Aluminum 6063-T5 alloy. The nose cone is made of carbon fiber and follows the Haack Von Karman profile. It has a wall thickness of 1 mm and a diameter of 160 mm. The first 65 mm is made of aluminum.
The rocket consists of three body tubes, each 700 mm long. The sections are connected with two specially designed couplers. The inner diameter is 156.4 mm, and the outer diameter is 160 mm.
The parachute system uses a CO2-based separation mechanism with 16 g CO2 cartridges. The parachutes are made of ripstop fabric and use a reinforced 10 kN shock cord compliant with ISO 2307.
Electronics and Avionics
The rocket features an 8-channel avionics system and an RF communication system operating at 433 MHz with 500 mW output power.
The main processor is a 32-bit, 100 MHz MCU, developed to record and analyze precise flight data.
Scientific Mission
The ATA rocket carries a multifunctional payload capable of collecting atmospheric data and performing scientific tasks. The rocket’s primary mission is to detect metal-containing meteors.
This system was developed to assist researchers studying the magnetism of extraterrestrial materials.
