比奇17斜罩型(两翼之间形成翼阶)飞机于1932年首飞,是比奇飞机制造公司第一种量产机型,由旅行飞机制造公司(怀特·比奇、苏德·塞斯纳和里德·斯迪尔曼在1931年合资建立)的泰德·威尔士设计。比奇斜罩是美国三四十年代较出色的飞机,虽在机体结构还是典型的木制结构,没有太大的进步,但它却有与众不同的流线外型和独特的机翼结构,而且与众不同的设计改善了飞行员的视野,增加了飞机的载荷,提高了飞机的抗失速性能。经过17年的生产,比奇斜罩出现了很多机型,而且在这段时间,飞机各方面的性能也逐步得到改善。早期的A-17采用是固定式的起落架,B-17后继型则将起落架改为可收放式。1937年生产的D17机身延长了45厘米,机冀和悬臂式的尾部都进行了改进,并且还采用了全新的风挡设计。1938年,比奇的E-17采用了支撑式尾翼和比较便宜的JACOBS发动机。最后的G17S是基于D17的改进型,主要特色来自它强劲的普惠R985型发动机,较低的阻力系数和更人性化的风挡设计。比奇17斜罩的生产在1949年结束,期间一共生产了781架。虽然比奇17主要用于民用航空,但在军事飞机领域上也可以见到它们的身影,如用于执行联络和通讯任务。美国空军就曾订购了207架比奇公司设计生产的UC-43,同时美国海军也订购了63架GB-2。除了美国,比奇17型飞机还出口到英国,巴西以及其他国家(如新西兰和澳大利亚)作区域运输之用。
BEIJING 17 Inclined plane (wing-level formation between wings) The plane, which first flew in 1932, was the first production model of the Beechcraft Aircraft Manufacturing Company and was operated by Travel Aircraft Manufacturing Company (White Beach, A joint venture between Sna and Reed Stilleman in 1931). The Beech Inclined Cap is an outstanding aircraft from the 1930s to the 1940s in the United States. Although it has not made much progress in body structure or typical wooden structure, it has a distinctive streamline appearance and unique wing structure , And unique design to improve the pilot’s vision, increasing the aircraft’s load and improve the anti-stall performance of the aircraft. After 17 years of production, many models appeared in the Beech Inclined Cap, and the performance of all aspects of the aircraft has also been gradually improved during this time. Early A-17 uses a fixed landing gear, B-17 successor changes the landing gear retractable. The D17 fuselage produced in 1937 was extended by 45 cm, both the Ji-Ji and the cantilever tail were improved, and a new windshield design was adopted. In 1938, the Beechcraft E-17 used a prop-tail and a cheaper JACOBS engine. The final G17S is an improved version based on the D17, the main feature comes from its strong Pratt & Whitney R985 engine, lower drag coefficient and more user-friendly windshield design. The production of the Beach 17 Inclined Shaft ended in 1949, during which a total of 781 aircraft were produced. Although Beech 17 is mainly used for civil aviation, they can also be seen in the field of military aircraft, for example, for performing liaison and communications tasks. The U.S. Air Force ordered 207 UC-43s designed and manufactured by Beechcraft, and the U.S. Navy ordered 63 GB-2s. In addition to the United States, the Beech-17 aircraft are also exported to the United Kingdom, Brazil and other countries such as New Zealand and Australia for regional transport.
