Development of Laser Ignition System for Solid Rocket Motor onboard Ultra-small Lunar Lander OMOTENASHI
Dr. Naoki Morishita has developed a laser ignition system for an ultra-small solid rocket motor to be mounted on the 6U-CubeSat "OMOTENASHI," the smallest ever lunar lander. The results have been published in Science and Technology of Energetic Materials as the following paper.
In the article, “Development of a laser ignition system for a solid rocket motor on the OMOTENASHI spacecraft", a short motor simulating the rear part of a rocket motor is used to perform an atmospheric ignition test to determine the required laser power density. In addition, by measuring the internal motor pressure and ignition delay in a vacuum state, he has obtained the data necessary to determine the optimum ignition timing for a lunar landing. The development was successful, and the ultimate miniaturized laser ignition system with a total system weight of 100g is installed on the spacecraft.
Dr. Naoki Morishita's research results are highly evaluated, and his significant contribution to Japan Explosive Society is worthy of Encouragement Award.
