立方直升机的这种配置让他可以像直升机一样盘旋，但在向前飞行时，主旋翼的转速可以将下来，让两侧的机翼提供升力，在此情况下，两台螺旋桨推进器就能发挥大作用了。
This means it can hover like a helicopter, but when flying forwards can reduce the speed of the main rotor and let the wings provide part of the lift. Its propellers give the extra oomph.
那么其他的一些飞行器，比如说直升飞机，螺旋桨飞机，他们没有喷气式引擎，可以在这种条件下飞行吗？
So can other aircraft, such as helicopters or prop-planes that don't have jet engines, fly through these conditions?
这种螺旋桨通常装在飞行员后面的一个桅杆上，起飞的时候升起（或在帮飞机实现更高的高度或航程的时候），随后收入机身。
The propeller is usually mounted on a mast behind the pilot and raised for take-off (or to gain more height or distance once airborne) and then lowered back inside the fuselage.
这种情况对飞行员来说很糟，因为螺旋桨的尖部接近声速(在海拔较低的温度下大约1200kph)，冲击波造成强烈震动。
And to make matters worse for the pilot, as the tips of the rotor blades approach the speed of sound (around 1,200kph at lower altitude temperatures), shock waves produce huge vibrations.
Pilobolus剧团以吸收不同寻常的元素出名，不过最为新奇的恐怕要属这两个在乔伊斯舞台上为舞者MattDelRosario伴舞的四螺旋桨直升机（学名“四旋翼飞行器”）。
Pilobolus is known for dances that incorporate unusual elements. Few, though, have been stranger than the two four-rotored helicopters that accompanied Matt Del Rosario on the stage of the Joyce.
彼特•斯扎帕里（Peter Szapary）是一位成为肯尼亚花农的奥地利伯爵，他驾驶着自己那架小型的螺旋桨驱使的飞机在东非大裂谷的内瓦沙镇的上空倾斜而过并保持着低空飞行。
THE small propeller-driven plane piloted by Peter Szapary, an Austrian count turned Kenyan flower farmer, banked and flew low over the Rift Valley town of Naivasha.
飞机采用非气密舱和四台动力不足的涡轮螺旋桨发动机，使它仅仅适用于低-中空飞行。
The aircraft has an unpressurised cabin and four underpowered turboprop engines, making it only suitable for low- to medium-altitude flight.
他没有在飞行过程中看到火或烟，他认为螺旋桨在旋转。
He saw no fire or smoke during the flight and he believed both propellers were rotating.
在没有退出螺旋俯冲并直线飞行之前不要放开耳朵。
Do not let go of the ear before exiting the spiral dive and flying straight.
飞机螺旋式的翻滚飞行。
螺旋桨只是摆在飞机前面给飞行员扇风的大扇子。等它不转了，你就等着看飞行员汗如雨下吧。
The propeller 'is just a big fan in front of the plane used to keep the pilot cool. When it stops, you can actually watch the pilot start sweating.
螺旋浆其实只是一个令飞行员凉快的大风扇，当它停了，基本上你会看到飞行员开始冒汗了…
The ropeller is just a big fan in front of the lane used to keep the ilot cool. When it stops, you can actually watch the ilot start sweating.
我的飞行机器既没有翅膀也没有螺旋桨，您可能会看到它在地上，和你绝不会猜到它是一架飞行机器。
My flying machine will have neither wings nor propellers. You might see it on the ground and you would never guess that it was a flying machine.
飞机各种能够飞行的带翼交通工具，通常比空气重，用喷气式发动机或螺旋桨驱动。
Any of various winged vehicles capable of flight, generally heavier than air and driven by jet engines or propellers.
最后结合飞行实例，进一步分析了螺旋桨气流斜吹给飞行带来的偏差。
And it also analyses further the deviation taken by PACTB in flight by combining the flight examples at last.
这个方法用一条目标曲线，几个螺旋桨桨叶角，模拟了飞机的10个飞行状态。
By using an objective curve and several propeller blade-angles, 10 flight states of aircraft are simulated.
