چکیده:
Considering the military implementation prohibitions and highly developed technologies of composite materials , this project studies about increasing the power of martial and fire in Gyroplanes and light Helicopters by design, optimization and manufacturing of composite launchers instead of isotropic types. Using composite type launchers have advantage of lower weight, higher life and
simplicity in manufacturing. Modeling and analysis accomplished by Abaqus Software and the fiber
composite directions improved by coding in Matlab Software. The optimization process completed by
linking both softwares. Till now, more than 800 successful shots have been made in several centers
using composite launchers. Because of easy manufacturing of this kind of launchers, there is no need to have advanced equipments and all the works have been provided by semi-skilled workers in the simple workshops.

Conclusion and the results of genetic algorithm code and mathlab and Abaqus software links for composite cylindrical (launcher) UCT Journal of Research in Science ,Engineering and Technology The final optimized results for composite Fiber made of graphite epoxy are presented in table 5.
The results show that some principles and criteria to locate villages having tourism attractions include density, residential places and tourism installations and tourism facilities, public facilities, employment, transportation, allowed threshold in environment, comfort threshold and natural thresholds.
To distribute the tourism services in a rural area according to the current capacity, limits to acceptable change, zoning, license and permission, environmental standards and designing criteria should be considered.
Distribution of tourism services in places having attraction and intervention in existing area necessitate the existence of certain rules and regulations and correspondence with local conditions.
Given that the residential centers are reciprocally related with agencies, attractions, the commercial and local environment, previous and next targets of tourist and has an important effect in increasing the duration of the tourist‟s visit (Mostofi Sadr, 2001) and the situation of these centers is considered as the most important factor in their success, locating these centers should be done methodically and precisely, and they should be built in locations that be visible and available to the travelers and as far as possible be close to the main road and road cross-sections, airports, commercial and industrial centers or promenades (Nasseri, 1996).
