In fact, the prototype Air Force outfit used to test out the gear is more garage nightmare than Hollywood blockbuster.

事实上，测试装备时穿的空军军服雏形要比好莱坞大片里看起来更令人恐怖。

The experiment proved that the gear meshing force, excitation frequency is consistent with the theory. Consistent with the actual prototype model is feasible.

通过实验证明齿轮的啮合力、激振频率均与理论相符，样机模型与实际吻合，具有可行性。

With the help of a machinist, and using a formula he concocted for a stiff, self-lubricating plastic, Fenelon built a crude prototype of the gear and found that the torque required to push the window was half of what the old design required.
