nosewheel (飛機的)降落前輪。

Whereas many taildraggers can afford to use non - retracting gear with minimal impact on performance , planes with nosewheels almost always require retraction mechanisms to reduce drag 另一方面,固定式后三點起落架耐沖擊性能較強。而前三點起落架,需要收放式以減小飛行時的阻力。

Another critical factor when designing tricycle gear is to properly balance the load carried by the main gear versus the nosewheel 前三點起落架的另一個不利因素,設計時需要較精確的分配主輪與前輪的負荷
