摘要

This concept allows us to launch a reusable launch vehicle (RLV) by incorporating Jato thrusters (Jet - fuel Assisted Take Off) and Magnetic Levitation runway. This advanced space launch system using Jato + Maglev can attain maximum takeoff speed within 30-40 seconds. This concept envisages the use of Magnetic Levitation using Electro Magnetic Suspension (EMS) for launching a vehicle at high take-off speeds and then using the Scramjet engine assisted by Apogee thrusters to propel it to the Thermosphere layer of the atmosphere and then deploy the payload canister. Then laser sail propulsion is used as a futuristic medium for interstellar travel. It uses a powerful laser system positioned within the solar system (in orbit around Jupiter) and a spacecraft with a large ultra-thin Mylar laser sail, which is propelled by the photon pressure of the laser beam emanating from the source. We propose a staged- sail concept, in principle making a deceleration at the target star system and even a round trip possible. However, our present concept has two significant drawbacks. First, the required laser power levels are extremely high and second, the pointing requirements for an eventual deceleration at the target star system are prohibitive. This paper presents approaches how innovative concepts for overcoming these two drawbacks can be created. We plan to use Theory of Inventive Problem Solving Technique (TRIZ), which provides a set of tools that are well-fitted to solve this type of problem. Furthermore, patterns are used by adding context information. As a result, attractive possibilities to remedy the laser sail propulsion concept are identified, e.g. the use of the gravitational lens of Jupiter, the fractionated spacecraft concept and the separation of cargo and crew. Our aim is to investigate these concepts in further detail in the future.
