内螺旋桨
摘要：
内螺旋桨涉及一种介质载体螺旋桨推进装置，其桨叶面积沿最大和较大旋转半径分布，桨叶分为前后两盘在桨毂上并列布置，叶根与旋转导管内壁固定，叶梢伸出的条辐与桨毂切交，桨毂和桨叶处于旋转导管之中。该桨具有推进效率高，结构紧凑，噪声低，振动小，制造容易等特点，适于用作舰船和螺旋桨飞机的推进装置。
摘要（英）：

Internal propeller is a propelling device of medium carrier. Its blade has area distributed along the largest and larger rotating radius and is divided into two, front and back, coils arranged parallelly on the propeller hub with the blade root being fixed on inner wall of rotary duct, the blade tip being tangential to propeller hub and the propeller hub and the blade being inside rotary duct. With high thrust efficiency, the said internal propeller is suitable for naval vessels and aircraft with propeller.
