Next Generation Avionics System Of Future Launch Vehicle

Abstract

Abstract:One new conception avionics system of launch vehicle is proposed according to the future technology trend. Aimed at efficient, low-cost and reliable space transportation system, the entire avionics system scheme is proposed innovatively in this paper. There are some characteristics in the avionics system as following: 1) The rocket-borne devices are miniaturization and standardization designed.2) The vehicle performs checkout intelligently and autonomously.3) The connection between rocket and ground facilities is simplified remarkably. 4) The launch facilities and operation is compacted greatly. 5) Launch control and management is mobile for the wireless networks utilized. 6) The cloud technology is used to build backbone network in the launch system. The onboard devices are designed to be highly intelligent so that the vehicle performs checkout autonomously. The rocket is connected to the ground support facilities, via a high-speed network, with rare cables. On the other hand, because many checkout equipments are fixed to rocket body, lots of ground support equipments can all be eliminated and the associated set-up time and the number of personnel involved can be reduced. Moreover, all the equipments are connected via a secured high-speed network, which make it possible to conduct the launch control anytime, anywhere in the world simply by using a single laptop computer or portable device such as mobile phone, pad etc. This means having an ultimate launch control system which is independent of launch sites. In the next generation launch system, a simpler launch system allows the frequent launch by largely-reducing operational costs through enhancing aspects of operational efficiency launch systems are improved and simplified. These innovative concepts will be a role model for future launch vehicles. IntroductionThe first flight of Japan's Epsilon launch vehicle, the newest version solid propulsion rocket, makes a great response in space domain on 14, Sep, 2013. Many original design concepts, such as the highly intelligent autonomous checkout system and the mobile launch control, are innovatively realized [1][2].The lift-off of Epsilon can be executed in less than 6 days after the rocket erected on launch pad. Moreover, JAXA has been conducting intensive researches on a next generation Epsilon to launch a more powerful and lower cost version Epsilon (E1) in 2017.America, Russia and Europe also have new programs to research and develop the next generation commercial launch vehicle aimed at low cost.The new launch vehicle aims at low cost and fast launch, which is mainly decided by the avionics system.With the development of electronic and communication technology, one scheme for next generation avionics system of future launch vehicle is proposed in this paper. The Top Design For Next Generation Avionics SystemThe Design Conception. In order to cut down the cost and improve the launch frequency, some new design ideas are needed to change the traditional work flow. Firstly, compared with traditional launc...
