For the first time in history, the ultimate in transportation is in sight. By the early 1980's travellers may zoom from the US to any point in the world in less than 45 minutes. Man simply can't travel any faster. Speeds higher than this would … hurl passengers and their craft into orbit. Exotic as it may seem, a preliminary design for such a craft has already been drawn up by Douglas Aircraft Company engineers. The Pegasus is a rocket transport capable of whisking 170 passengers, their baggage, and 18 tons of cargo high above the atmosphere from continent to continent at 17,000 miles per hour. Douglas engineers believe it could start coming off the assembly lines and into commercial service in 15 to 20 years . . .

Designer: Hughes. Propellants: Electric/Xenon Thrust(vac): 0.000 kgf. Thrust(vac): 0.000 kN. Isp: 2,585 sec. Mass Engine: 68 kg. Diameter: 0.26 m. Chambers: 1. Thrust to Weight Ratio: 0. Country: USA. Status: In Production. The development of the 18mN Xenon ion thruster subsystem for telecom satellites could have use in low force thrusters for attitude control. The Xenon ion propulsion subsystems (coined by Hughes Research Labs), or XIPS comprises four 13cm thrusters (two primary and two back-up) power supply. Each has 439W input off 29.34Vdc, and a propellant storage and control unit. The total XIPS system mass is 68 kg. The Hughes Company states that the system was developed from work on a 25cm dia 63.5cm thruster that provided Isp of 2800 secs at 1.3kW input.. Manufacturer: Hughes Research Laboratories. Thrust: 17.8mN. Beam Voltage: 751 V. Accelerator Voltage: -300 V. Beam Current: 0.405 A. Accelerator Current: 0.97 mA. Exhaust Velocity: 30 km/sec. Isp: 2585 sec. Beam Power: 304 W. Power/Thrust Ratio: 24.6 W/mN. Electrical Efficiency: 51.3%. Mass: 5.0 kg each thruster (x4). 6.8 kg each power processor (x4). 2.0 kg each Xe tank (x2).
