치차(치차장치)는 주어진 회전속도의 동력을 일하기에 알맞는 회전속도의 동력으로 바꾸는 장 치이다. 회전속도 변환장치에는 여러 가지가 있으나 치차가 가장 콤팩트하고 또 정확하다. 이 것을 능가하는 것은 없다. 치차 장치를 고속화시키고 더욱 콤팩트하게하면 진동의 뭍제가 뒤 따른다. 오차가 없는 정밀치차를 사요하고 윤활도 잘 하지 않으면 안된다. 그 외에도 축, 베 어링, 케이싱등 치차주변의 기계요소도 대단히 중요하다.

겨울철 영양 간식인 고구마. 추운 겨울 김이 폴폴 나는 고구마를 한입 베어물면 달콤한 맛에 입이 즐겁고, 따끈한 기운에 몸이 따뜻해 집니다. 여기에 각종 야채를 더해 닭가슴살로 돌돌 말아 튀겨먹으면 고구마의 달콤함과 닭가슴살의 부드럽고 담백한 맛이 더해져 한끼 식사는 물론 연말연시 손님 접대용으로도 손색이 없습니다.

In this study, we developed a gear-type vane damper which replaces the link type through a proper gear design by means of a finite element analysis. We analyzed the fluid flow according to the amount of angular displacement. torque and backlash problems were addressed in conjunction with the pinion as a structural improvement of the forced draft fan (FD FAN). Through an environmental test. Also, results nearly identical to those in the test could be drawn when using a numerical method. Finally, we compared the gear driving result with simulation results. objective of the present study is to identify a nonlinear flow rate control method for a gear-type vane damper and to propose a damper shape which offers linear flow rate control. This study is related to the development of a gear-type vane damper of the change-link type in a forced draft fan.

Thrust vector control system is a control device which is mounted on the exit of the nozzle to generate pitch, yaw and roll directional force by deflecting flow direction of the supersonic jet from the nozzle. Thermal and aerodynamic loads are acting on the surface of jet vane when it is exposed to the jet flow. Axial thrust loss and side thrust loss are affected by shock patterns and interactions between jet-vanes which varies with jet-vane geometry and turning angle. In this research, the performance estimation using the numerical simulation analysis of the nozzle is given and the investigation of the flow visualization and aerodynamic performance with the enforced power to the vane is taken.

In this study, we developed the gear type vane damper replacing the link type through gear design using Finite Element Analysis(FEA). FEA about the pinion and the vane shaft in the boss of gear type damper for quality improvement was accomplished. We analyzed fluid flow according to angular displacement. Catched the problem of the torque and backlash bring to the pinion as structure improvement of the forced draft fan(FD FAN). Finally, we compared the gear driving result with simulation. It is the objective of the present study to identify a nonlinear flow rate control of gear type vane damper and to suggest a damper shape with a linear flow rate control. This study is related to the development of gear type vane damper change link type in forced draft fan.
