Non-Rocket Missile Rope Launcher

Abstract: The method, installation, and estimation for delivering payload and missiles into outer space are presented. This method uses, in general, the engines and straight or closed-loop cables disposed on a planet surface. The installation consists of a space apparatus, power drive stations located along trajectory of the apparatus, the cables connected to the apparatus and to the power stations, a system for suspending the cable, and disconnected device. The drive stations accelerate the apparatus up to hypersonic speed. The estimations and computations show the possibility of making these projects a reality in a short period of time (see attached project: launcher for missiles and loads). The launch will be very cheap $1-$2 per LB. We need only light strong cable, which can be made from artificial fibers, whiskers, nanotubes, which exist in industry and scientific laboratories.

Artificial Aurora Experiments and Application to Natural Aurora

Abstract: A review is given of the effects observed during injections of powerful electron beams from sounding rockets into the upper atmosphere. Data come from in situ particle and wave measurements near a beam emitting rocket and ground-based optical, wideband radiowave, and radar observations. The overall data cannot be explained solely by collisional degradation of energetic electrons but require collisionless beam plasma interactions (BPI) be taken into account. The beam-plasma discharge theory describes the features of the region near a beam-emitting rocket, where the beam-excited plasma waves energize plasma electrons, which then ignite the discharge. The observations far beneath the rocket reveal a double-peak structure of artificial auroral rays, which can be understood in terms of the beam-excited strong Langmuir turbulence being affected by collisions of ionospheric electrons. This leads to the enhanced energization of ionospheric electrons in a narrow layer termed the plasma turbulence layer (PTL), which explains the upper peak. Similar double-peak structures or a sharp upper boundary in rayed auroral arcs have been observed in the auroral ionosphere by optical, radar, and rocket observations, and called Enhanced Aurora. A striking resemblance between Enhanced and Artificial Aurora altitude profiles indicates that they are created by the above BPI process which results in the PTL.

Slag mass accumulation in spinning solid rocket motors

Abstract: A series of specific solid propellant rocket motors are evaluated and their slag mass accumulation is computed when operating in strong acceleration environments. It is shown that the configuration of the propellant burning surface during the last 10 s of burning has a very strong effect on slag formation. Motors with front-end burning grains at burnout have maximum slag retention potential, whereas motors with the grain burning inside potential slag pockets (e.g., the buried nozzle cavities) do not accumulate any slag. The effects of the internal flowfield are significant because they are the direct result of the grain configuration. It is concluded that if slag is a problem, selective grain design will tend to minimize it or to eliminate it completely.

System and method for reducing dispersion of small rockets

Abstract: An active damping method and a self-contained active damping system that can be retrofitted to existing rockets are provided which for reducing the dispersion of rockets by using lateral thrusters to oppose any initial yawing motion. The self-contained system of the present invention can be installed in a cylindrical section of a rocket body by insertion between other flight body parts.
