Sukhoi Su-27 which has some of the best manoeuvrability in the world, teamed up with the Mikoyan MiG-29, as Russian “Warriors” and “Swifts”in a mixed formation in this year's air show.由機動性能世界領先的蘇—27，與米格—29戰斗機組成的俄羅斯的“勇士”和“雨燕”，以混合編隊亮相本屆航展。

Just like athletes pursuing “higher, faster, and stronger”in the Olympic games, aviation manufacturers are looking to push the boundaries of their industry.Come to the 2016 Zhuhai Air Show and fi nd out how.

In the aviation industry, companies are looking for stronger composite materials and more energysaving impetus.

At the 2016 Zhuhai Air Show, the Airbus 350 was one of the superstars.The aircraft displayed was the latest long-range, double-engine, wide-body test model.For it's airframe, 70% is made of cutting-edge materials, including titanium, composite materials, and aluminium alloy.It is made up of 53% composite materials, which ranks the top in the industry.Meanwhile, the plane's fuselage is entirely made of carbon fi bre reinforced plastics (CFRP), which largely reduces the weight and energy consumption.

In the aviation industry, the attempt to develop an aircraft that can fl y farther with less fuel has never stopped.The Bombardier's C-series planes have all adopted the PurePower PW1500G “geared turbofan” engine developed by Pratt &Whitney (P&W).It's special gearbox allows the balance of high-speed turbine and the low-speed fan at a lower speed, which proves capable of a 50% reduction in noise and 10% in emissions.

The other possible direction for energy saving is to improve the design of the wings.Well designed wings can induce a vortex that increases the lift whilst reducing the resistance for the plane during fl ight.At the 2016 exhibition, China's new-generation military transport jets, the Y-20, displayed its advanced design with the impressive vortex created during the air show.

Bombardier's CS300 has also been an impressive new-material user.70% of the fuselage is made of advanced structural materials.來自龐巴迪的CS300客機也是突出的新型材料使用者，70%的機身將由高級結構性材料制成。

A350's fuselage is made entirely of carbon fibre reinforced plastics (CFRP), which largely reduces the weight and energy consumption.A350機身全部采用碳纖維增強復合材料（CFRP）制造，大幅降低了重量和油耗。

The AG-600 aircraft, self designed and developed in China, use 4 domestic-made WJ-6 gas turbine engines and is the biggest ongoing amphibious aircraft in the world.中國自行設計研制的AG-600，選裝了4臺國產渦槳-6發動機，是世界在研最大的水陸兩用飛機。

CH-5 UAV uses the straight wings with a high lift-to-drag ratio to increase its endurance.The longest flying distance a of the improved aircraft can be over 10 thousand Kilometres.“彩虹-5”無人機選用高升阻比的平直機翼提升了續航能力，改進型的最大飛行距離將超過1萬公里。

Y-20 has been the largest aircraft developed by China.Its 47-meter length and 45-meter wing width almost equal the measures of a football field.And with a 15-meter height, it is as tall as a 5-storey building.運-20是我國迄今研制的最大飛機，全長47米、翼展45米、高15米，長寬相當于半個足球場，高度約有5層樓高。

當人類在奧林匹克運動會上追求更高更快更強的時候，航空界在追求什么呢？2016年珠海航展，可窺一斑。

在航空界，人們一直在尋找更高強度復合材料，更高效的動力。

本屆珠海航展現場，空客A350也因此是當之無愧的明星。這架最新雙發遠程寬體客機A350WXB測試飛機，有超過70%的機體結構采用鈦復合材料、新一代鋁合金等先進材料制造，其中復合材料使用率達53%，為業內最高。同時，機身全部采用碳纖維增強復合材料（CFRP）制造，大幅降低了重量和油耗。

在動力方面，人們一直把航空飛行器設計改進的方向定位在，運用更少的油耗飛行更遠的距離。比如龐巴迪的C系列飛機搭載普惠公司的PurePower PW1500G齒輪傳動渦扇發動機，運用齒輪減速系統，匹配渦輪和風扇的平衡，可以降低50%噪聲與10%排放。

改進翼型設計也是節省動力的重要方向。先進的機翼可以誘發渦流，利用好渦流可以增加升力特別是大迎角時的升力，也可以消除機翼負面層堆積增厚，從而減少飛行阻力。本次航展中，作為中國自主研發的新一代噴氣式大型軍用運輸機“鯤鵬”運—20，在機動飛行時能拉出渦流，可見翼型設計是相當先進的。
