| 1. | Naturally, the helix angle is the geometric complement of the lead angle.
|
| 2. | Lead angle is the angle between the helix and a plane of rotation.
|
| 3. | Instead, the lead angle, which is equal to 90 degrees minus the helix angle, is given.
|
| 4. | An equivalent comparison is when the friction angle is greater than the lead angle ( \ phi > \ lambda ).
|
| 5. | Gun lead angles meant that gun-stabilizing commands differed from those needed to keep the director's sights stable.
|
| 6. | Lead angles and corrections were added to the LOS data to generate the line-of-fire ( LOF ) data.
|
| 7. | The reticle pattern determines accurate firing of up to 400 metres and can predict the correct lead angle for a moving target.
|
| 8. | Whether a worm and gear is self-locking depends on the lead angle, the pressure angle, and the coefficient of friction.
|
| 9. | The helix angle references the axis of the cylinder, distinguishing it from the lead angle, which references a line perpendicular to the axis.
|
| 10. | The usual autocannon burst consists of 3 10 projectiles and target lead angle is calculated for each burst ( fire without adjustment ) by computer.
