What will be achieved by the design of SAX 40? [br] What will be the result of designing the body of SAX-40 as tailless and triangular?
选项
A、This shape can make the airplane fly faster.
B、This shape can hold more passengers.
C、This shape can supply more power raising.
D、This shape can be flied easily.
答案
C
解析
根据题干SAX-40可以定位到第四段第二、三句,谈论SAX-40机身的形状和这样设计的目的。根据本段第三句可知把机身设计成没有尾翼的三角形,是因为这种形状可以提供更多的提升力,这样就能使飞机在起降时速度慢下来。这种形状能否使飞机飞行时变快本段没说明,但它在起降时减慢飞行速度是确定的,故排除A;这种形状的飞机是否能容纳更多乘客,本段没说明,故排除B;这种形状的飞机是否容易驾驶本段未说明,但最后一段第三句指出这种形状的飞机难于驾驶,故排除D。
