Catapult Transportation

Authors: Alexander Bolonkin

The current flight passenger-transport and cargo systems have reached the peak of their development. In the last 30 years there has been no increase in speed or reductions in trip costs. The transportation industry needs a revolutionary idea, which allows jumps in speed and delivery capability, and dramatic drops in trip price. The author offers a new idea in transportation in which trip (flight) time practically does not depend on distance, and vehicle load capability doubles and which has a driving engine that is located on the ground and can use any cheap source of energy. The author develops the theory and provides computations for project contains five subprojects united the common idea: acceleration the air vehicle on ground and continuation of flight by inertia (high speed catapulting). The initial speed is 290 – 6000 m/s, the range is 50 -10000 km (short, average, and long distances). Short transport system has range 50-70 km, for example: city – sub-city, strait and air bridges such as across the Straits of Gibraltar 16 km, the English Channel 40 km, Bering Straits 100 km (Russia–America), Sakhalin–Asia 20 km, Russia–Japan, etc. The long distance has range up 10000 km such as New York-Paris 5838 km, Washington-London 7373 km, San-Francisco – Tokyo 8277 km, San-Francisco – Vladivostok (Russia) 8377 km, New York – Moscow 7519 km, Moscow – Beijing 5800 km, Moscow – Tokyo 7487 km, New York – Berlin 6392 km, and so on. The offered catapult system having length 400 km can be used as the space launch system which decreases the space launch cost in hundreds times. That also may be used as the new conventional high speed (up 1000 km/h) transport system between cities. That will be significantly cheaper then used MagLev (Magnetic Levitation) systems, because for suspending of the vehicle used the conventional wing. The offered system may be also used for the mass launch of bombs (projectiles) in war. ------------------- Key word: air catapult transport, air kinetic transport, new passenger and cargo transport, catapult aviation, new space launch system, new suspending high speed ground system, cattran, skimplane. *Detailed manuscript AIAA-2005-6221 was presented to Atmospheric Flight Mechanic Conference – 2005, 15–18 August, USA.
