雅科夫列夫UT-1 – 照片和视频

这 雅科夫列夫 UT-1 (Russian: УТ-1) was a single-seater trainer aircraft used by the Soviet Air Force from 1937 until the late 1940s. The UT-1 was designed as a single-seater advanced trainer and aerobatic airplane by the team led by Alexander Sergeevich Yakovlev. The first prototype, designated the AIR-14, was flown in early 1936. The AIR-14 was a small low-winged monoplane with a fixed tailwheel undercarriage, with a welded steel fuselage and wooden wings. After some changes, the AIR-14 was accepted for production. Among other improvements, the 75 kW (100 hp) Shvetsov M-11 radial was changed to the more powerful 86 kW (115 hp) M-11G. The plane received the designation UT-1 (uchebno-trenirovochnyi {учебно-тренировочный}, primary/advanced trainer); despite this designation, it was not suitable for primary training.

雅科夫列夫UT-1是苏联空军从1937年到1940年代后期使用的单座教练机。它由亚历山大·谢尔盖耶维奇·雅科夫列夫设计，作为单座高级教练机和特技飞机。第一架原型机被命名为AIR-14，于1936年初试飞。AIR-14是一种小型低翼单翼飞机，带有固定尾轮起落架，带有焊接钢机身和木制机翼。
UT-1不适合初级训练，但它被用作UT-2和I-16等战斗机之间的过渡类型。它需要精确的驾驶，从而在基本教练机和机动但难以飞行的I-16之间形成理想的中间体。UT-1在生产过程中经历了几次修改，包括发动机，机身长度和机翼形状的变化。一些UT-1也被改装成简易战斗机器，装有机枪或火箭，并在第二次世界大战期间用于侦察或对地攻击任务。
UT-1还用于在战前创造多项记录，其中一些带有水上飞机变体。1936 年 12 月至 1940 年间，总共制造了 1，241 架飞机。UT-1 在 18 年代被雅科夫列夫 Yak-1950 取代。
