The purpose of this paper is to perform the feasibility and performance evaluation of the High-altitude launch technique using high altitude atmospheric Properties to near earth orbits. The current propulsion transportation system from Earth to space has been deemed by many to be expensive, unreliable, and an unnecessarily dangerous means of travel to space. It is suggested in this paper to ana...

Existing engineering materials allow the constuction of towers to heights of many kilometers. Orbital launch from a high altitude has significant advantages over sea-level launch due to the reduced atmospheric pressure, resulting in lower atmospheric drag on the vehicle and allowing higher rocket engine performance. High-altitude launch sites are particularly advantageous for single-stage to or...

Two liter bottle rockets made from recycled soda bottles are often used in high school science classes and in introductory college courses. Typically, it is often more challenging to shoot bottle rockets for distance instead of shooting them straight up and measuring altitude, as is often done. Using a device made from pipe and wood to launch bottle rockets and control the launch angle creates ...

An understanding of the characteristics of trajectories of constant-altitude stratospheric platforms is important for scientific balloon flights because science observation sequences, safety planning, overflight negotiations, launch site selection, and recovery operations are affected by trajectory. Supported by NASA, Global Aerospace Corporation (GAC) has developed a Trajectory Simulation and ...

The sounding rocket for the DELTA (Dynamics and Energetics of the Lower Thermosphere in Aurora) campaign was successfully launched from Andoya at 00:33 UT on Dec 13, 2004. Though it was cloudy at the time of launch, the Weber Na lidar was operating intermittently between 20:00 UT and 23:30 UT on Dec 12, observing Na density, temperature and meridional wind between 80 and 100 km. Throughout the ...

The demand for wireless communication is increasing day by day. People want a high speed of communication in less time. No one is interested in use of bunch of wires. So we move to wireless communication. As technology increases a demand also increases. Now everyone wants a fast communication from anywhere to anyone. Even rural area also requires internet facility. It is too hard to establish a...

Airborne wind energy systems with a rotary wing and a ground generator are analyzed. These systems are very attractive from practical point of view, because of absence of tether drag, simplicity of control, launch and landing of the wing, combined with the well known benefits of AWES, including ability to reach high altitude winds and to adjust altitude dynamically to catch the strongest wind. ...
