Lifeboat Waverider and Ark I habitat
|
Ark I is a self-sustaining space colony built to ensure humanity could survive disasters that make Earth uninhabitable such as nanoweapon disasters or mishaps in particle accelerator experiments. We are moving towards a world with less and less privacy. Credit card reports and bank records are available to almost everyone, your phone calls are tapped, cameras are being placed everywhere, etc. This will only get worse when more powerful weapons are available to the individual. In the future, if you wanted a lot of privacy, you couldn't live with billions of people whose lives depended on what you did. So instead you could live on a small spaceship with a couple thousand people who trusted each other. Ark I will have a permanent population of 1,000 people with a capacity for 500 visitors.Lifeboat WaveRiders, to be used by Ark I for cargo, construction and travel purposes, are uniquely designed on an operative principle very different from that of conventional aircraft. WaveRiders "surf" on their own shock waves. Gliding at supersonic speeds, the WaveRider's passage through the atmosphere creates a shock wave, which is trapped in an aerodynamic trough on its underside. Trapping the shock wave generates several very important effects: First, the sonic boom is greatly minimized, since the bulk of the shock wave is contained within the trough. Second, compression drag, and its attendant heating of the capsule are significantly reduced. (This will enhance the systems overall efficiency and ease engineering and maintenance problems.) Third, much of the energy in the shock wave goes to generate lift, giving the WaveRider, a tremendously increased glide ratio. (Ten times the lift-to-drag ratio of conventional hypersonic designs.) Each WaveRider can carry 72 passengers using 6 seats across, with 2 pilots and 2 additional crew. The hangar that WaveRiders dock in is not normally pressurized, instead passengers enter through an extensible tube similar to what is common at airports.Credits: Lifeboat Foundation
