“It’s a Delta Wing, but it’s called an ogival delta wing because of its unique shape.”

“这是一个三角翼， 但由于其独特的形状， 它被称为尖角三角翼。”

For example, the delta wing designed to minimize drag at high speed but maximize lift at take off was the result of over 5,000 hours of wind tunnel testing.

例如，三角翼的设计是为了在高速时减少阻力，但在起飞时增加升力，这是超过5000小时风洞测试的结果。
