北美O-47 – 照片和视频

这 北美O-47 is an observation fixed-wing aircraft monoplane used by the United States Army Air Corps. It had a low-wing configuration, retractable landing gear and a three-blade propeller. The O-47 was developed as a replacement for the Thomas-Morse O-19 and Douglas O-38 observation biplanes.

这 北美O-47 was an observation fixed-wing aircraft monoplane that served in the United States Army Air Corps before and during World War II. It was designed by North American Aviation in the mid-1930s as a replacement for the older biplane observation aircraft. The O-47 had a low-wing configuration, retractable landing gear, and a three-blade propeller. It was powered by a Wright R-1820 radial engine that produced 975 horsepower. The O-47 had a crew of three: a pilot, a co-pilot/observer, and a rear gunner. The aircraft was equipped with a fixed forward-firing machine gun in the right wing and a flexible rear-firing machine gun in the cockpit. The O-47 also had windows in the belly to allow downward observation and photography.
O-47最初由空军于1937年订购，到1938年交付了174架。他们中的一些人被分配到国民警卫队。1938年，订购了改进版O-47B，共生产了74架。O-47B具有重新设计的发动机整流罩，升级的发动机和改进的无线电设备。它还有一个额外的油箱来增加其航程。O-47B的速度稍快，可以比O-47A飞得更高。
O-47旨在执行观察和侦察任务以支持地面部队。然而，随着更新更快的飞机的出现，它很快就过时了。O-47 太慢了，容易受到敌方战斗机和防空火力的攻击。它的机动性和能见度也有限。1941年，训练演习表明，像Piper L-4和Stinson L-5这样的轻型飞机更适合与地面部队作战，而战斗机和轰炸机则更有效地执行侦察和拍照任务。结果，O-47被降级为次要角色，如海岸巡逻，反潜巡逻和目标牵引。一些O-47也被在菲律宾的日军俘虏并用于对付盟军。
这 O-47 was retired from service after World War II. Only a few examples survive today in museums or private collections.
