초록

본 연구에서는 피치각 가변형 축류팬의 성능(정압별 풍량, 소비전력)과 소음특성을 실험으로 구하였다. 피치각은 $20^{\circ}{\sim}45^{\circ}$로 $5^{\circ}$ 간격으로 6개의 각도를 변화시켜 가면서 측정 하였고 팬 날개는 동일한 에어포일 형상으로 길이는 80 mm, 90 mm, 100 mm, 110 mm, 120 mm로 변경하여 실험을 수행하였다.

In this study, the performance of an impeller according to blade length and pitch angle was studied experimentally by building a variable pitch impeller while changing blade length to review the effect of blade length and pitch angle on a fan's performance and sound characteristics. The pitch angle was changed in six steps from $20^{\circ}{\sim}45^{\circ}$ at intervals of $5^{\circ}$ while the blade lengths were changed 80 mm, 90 mm, 100 mm, 110 mm and 120 mm with an identical airfoil shape while carrying out the experiment.
