Selection Of

In order to realize propulsion system and oxygen system of tourist submarines be secure, eco-friendly, efficient, reliable, economical, a combination of ordinary air motor and ACM high-pressure air bottle is adopted for providing propulsion and oxygen. The calculation and selection of the appropriate air motor and high-pressure bottle are based on the propulsive requirement of a tourist submarine. A model consists of high-pressure bottle, air motor, propeller and the resistance of the tourist submarine is established in SimulationX. The underwater speed and it’s duration are obtained through calculation as the rev, thrust force, torque of the propeller, etc. The possibility of application of pneumatic propulsion method in tourist submarine is analysed. Results illustrate that: on the premise of lightened quality of the propulsion system, pneumatic propulsion method fulfills the required underwater speed and it’s duration.

Aircraft Motion

Abstract the dynamics of aircraft motion is determined, as is well known, by the acting forces. When an airplane is flying, these forces include the total aerodynamic force, the thrust force of the propulsion system, and the force of gravity. Hybrid Airship differs from an aircraft by the presence, in addition to the above, of aerostatic force, the value of which depends, among other things, on the height of flight of the Hybrid Airship. The presence of aerostatic force affects the maneuverability of a Hybrid Airship. The proposed article analyzes the changes in the characteristics of a Hybrid Airship turn caused by the presence of aerostatic force.

Fire Fighting Robot

A suspended fire fighting robot was presented, and the prototype was developed. The robot changed its posture by the blowing forces from the fans; the PID algorithm was analyzed and applied to control the rotating speeds of the fans in order to realize posture adjustment. A high speed propeller driven by an engine pushed the robot approach to the target; the relation between steering angle and thrust force was studied; a sliding table structure was developed to make the robot move steadily by changing the gravity position; the control algorithm of the propulsion system was analyzed.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
