Abstract

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.

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.
