以及Everything in the pilot's room made her so excited.飞行员房间里的一切都让她兴奋不已。可以推测出,阿吉拉德认为去机场参观又酷又刺激。故选B.(3)D.细节理解题。根据During the trip,students were also given lectures about how to build a plane and how to make it fly.在这次旅行中,学生们还...
Today in science class, we made paper airplanes. Our teacher said, “We will see which airplane___ the farthest.”The teacher had a___. She measured how far each airplane travelled. Some airplanes didn't go far. They flew only two meters and ___ on to the floor....
Airplanes are also sometimes fitted with stick pushers. The pusher system physically pushes the controls if the aircraft comes close to a stall. How airplanes are designed to delay the stall The delaying of a stall is important as it allows the manufacturers to build an aircraft that has better...
However, when these airplanes are taking off or landing, their speeds can be reduced to less than 200 miles per hour (322 kilometers per hour). This dramatic change in the wing's working conditions means that a different airfoil shape would probably better serve the aircraft. Airfoil shapes ...
In this experiment, the robot made and launched over 500 paper airplanes with 50 different designs. Then it collected data on how far each design flew and the characteristics of that flight. The researchers sorted different shapes roughly into three types of “behavioral groups”. The first type...
Finally, the ethanol produced in the previous stage is utilized as a fuel source for various modes of transportation, such as cars, trucks, and airplanes. During this utilization phase, ethanol undergoes combustion, releasing carbon dioxide back into the atmosphere. This carbon dioxide is then re...
One observation that can be made from figure 7 is that the top surface of the wing does much more to move the air than the bottom. So the top is the more critical surface. Thus, airplanes can carry external stores, such as drop tanks, under the wings but not on top where they would...
