这 T-62 是1961年首次引进的苏联主战坦克。作为T-55系列的进一步发展，T-62保留了其前身的许多类似的设计元素，包括低姿态和厚炮塔盔甲。与以往配备步枪坦克枪的坦克相比，T-62是第一辆配备平滑体坦克枪的坦克，可以以更高的速度发射APPFSDS子弹。虽然T-62成为苏联武器库的标准坦克，但由于其制造成本和维护要求高于其前身，它并没有完全取代出口市场的T-55。虽然T-62在俄罗斯和苏联的继承国被取代，但在一些国家仍然使用，其设计特征在随后的苏联和俄罗斯大规模生产坦克中变得标准化。

这 维克斯 · 维斯计数 was a British medium-range turboprop airliner first flown in 1948 by Vickers-Armstrongs. A design requirement from the Brabazon Committee, it entered service in 1953 and was the first turboprop-powered airliner. The Viscount was well received by the public for its cabin conditions, which included pressurisation, reductions in vibration and noise, and panoramic windows. It became one of the most successful and profitable of the first post-war transport aircraf, 445 Viscounts were built for a range of international customers, including in North America.

拉克-V (Lighter, Amphibious Resupply, Cargo, 5 ton), is an aluminium-hulled amphibious cargo vehicle capable of transporting 5 tons. It was developed in the United States during the 1950s, and is used in a variety of auxiliary roles to this day. In addition to the United States, Larc-Vs have been used by military forces in Australia, Argentina, Portugal, Philippines, Singapore and Iceland. Approximately 968 were made. About 500 were destroyed, most by scuttling during the American withdrawal from South Vietnam. About 200 have been retained in U.S. military service. Roughly 100 are privately owned and mostly used for tourism. These include tourist trips on the Jökulsárlón ice lake in Iceland and city and harbour tours in Halifax, Nova Scotia.

The Avro Canada VZ-9 Avrocar was a VTOL aircraft developed by Avro Canada as part of a secret U.S. military project carried out in the early years of the Cold War. The Avrocar intended to exploit the Coandă effect to provide lift and thrust from a single “turborotor” blowing exhaust out the rim of the disk-shaped aircraft. In the air, it would have resembled a flying saucer. Originally designed as a fighter-like aircraft capable of very high speeds and altitudes, the project was repeatedly scaled back over time and the U.S. Air Force eventually abandoned it. Development was then taken up by the U.S. Army for a tactical combat aircraft requirement, a sort of high-performance helicopter. In flight testing, the Avrocar proved to have unresolved thrust and stability problems that limited it to a degraded, low-performance flight envelope; subsequently, the project was cancelled in September 1961.

这 缩放复合材料型号 348 White Knight Two (WK2) is a quadjet cargo aircraft that is used to lift the SpaceShipTwo spacecraft to release altitude. It was developed by Scaled Composites from 2007 to 2010 as the first stage of Tier 1b, a two-stage to suborbital-space manned launch system. WK2 is based on the successful mothership to SpaceShipOne, White Knight, which itself is based on Proteus. With an “open architecture” design and explicit plans for multi-purpose use, the aircraft could also operate as a zero-g aircraft for passenger training or microgravity science flights, handle missions in high-altitude testing more generally, or be used to launch payloads other than SpaceShipTwo. A study of use of the aircraft as a forest fire water bomber has also been mentioned, one that would utilize a large carbon composite water tank that could be quickly replenished to make repeat runs over fires.

这 诺斯罗普X-4班坦 是诺斯罗普公司1948年制造的小型双喷气飞机的原型。它没有水平尾部表面，而是依靠联合电梯和艾龙控制表面（称为升降机）来控制音高和滚动的态度，几乎完全按照纳粹德国Luftwaffe的类似格式，火箭驱动的Messerschmitt Me 163的方式。一些空气动力学家曾提出，消除水平尾部也会消除由机翼和水平稳定器的超音速冲击波相互作用导致的高速稳定性问题（称为冲击停滞）。这个想法是有价值的，但当时的飞行控制系统阻止了X-4的任何成功。

这 布里斯托尔170型货船 was a British twin-engine aircraft designed and built by the Bristol Aeroplane Company as both a freighter and airliner. Its best known use was as an air ferry to carry cars and their passengers over relatively short distances. A passenger-only version was also produced, known as the Wayfarer. The Freighter was developed during the Second World War, having attracted official attention from the British Air Ministry, which sought the development of a rugged vehicle capable of carrying various cargoes, including a 3-ton truck. Various changes to the design were made to accommodate their requirements, but being completed too late to participate in the conflict, the majority of sales of the Freighter were to commercial operators. In response to customer demand, an enlarged version to maximise vehicle-carrying capacity, known as the Bristol Superfreighter, was developed.
