Do multi engines face the torque effect? What about jets?

    By "torque effect" do you mean p-factor? Or some kind of rolling effect due to a high power engine? – Ron Beyer May 14 '17 at 01:36

    @RonBeyer to be fair, if the OP understand the difference between torque and p-factor, he would not be asking this question. – kevin May 14 '17 at 12:20
  • I know that the torque effect is the left-turning tendency an aircraft has. Don't know what p-factor is (the Wikipedia explanation is a bit complicated). Any videos? – TayE May 14 '17 at 13:11
  • With all engines operating or one or more engines inoperative? – J W May 16 '17 at 17:16

Maybe you mean the p-factor. If both engines are rotating clockwise, the plane yaws to the right. If one rotates clockwise, the other counter-clockwise, the effect cancelles out and the plane flys straight.

  • What about the effect of the two engines operating at different speeds? Is that significant? – Tanner Swett May 20 '17 at 23:16

    @TannerSwett I think so. The p-factor is directly proportional with the speed of the prop. Now, if one engine operates at a different speed, the plane will yaw into the direction of the faster engine. (Apart from the fact that the thrust is applied asymmetrically) – Noah Krasser May 22 '17 at 15:22
