MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202421062393 A) filed by Vihaan Spacetech Private Limited, Nagpur, Maharashtra, on Aug. 17, 2024, for 'dual thrust armament rocket motor system.'
Inventor(s) include Rajesh Namdeorao Muneshwar.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a dual-thrust rocket motor system for 70 mm armament rockets, compatible with both guided and unguided configurations for air-to-ground and ground-to-ground applications. The system comprises a cylindrical motor casing (70 mm diameter, 322 mm length) housing a central smokeless double base propellant (DBP) grain and a concentric ammonium perchlorate high energy composite propellant (APHEC) grain. The DBP grain, with a central perforation of about 20 mm, initiates a boost phase of approximately 0.23 seconds, providing safe stand-off distance (~400-450 m) before ignition of the APHEC grain, which sustains propulsion at high specific impulse (2871 m/s) and low exhaust signature while eliminating solid particulate emissions. An innovative nozzle assembly enables rapid reconfiguration between air-to-ground and ground-to-ground missions. A tail assembly with four stabilizing fins ensures aerodynamic stability, and a modular forward payload interface allows quick coupling with high-explosive (HE), incendiary, or mission-specific warheads. The concentric dual-propellant arrangement provides seamless thrust transition, extended range, reduced visibility, and enhanced operational flexibility, representing a significant advancement in modern rocket propulsion technology."
