terminal velocity

n
1. (General Physics) the constant maximum velocity reached by a body falling under gravity through a fluid, esp the atmosphere
2. (Firearms, Gunnery, Ordnance & Artillery) the velocity of a missile or projectile when it reaches its target
3. (Firearms, Gunnery, Ordnance & Artillery) the maximum velocity attained by a rocket, missile, or shell flying in a parabolic flight path
4. (Aeronautics) the maximum velocity that an aircraft can attain, as determined by its total drag

terminal velocity

1. Hypothetical maximum speed a body could attain along a specified flight path under given conditions of weight and thrust if diving through an unlimited distance in air of specified uniform density.
2. Remaining speed of a projectile at the point in its downward path where it is level with the muzzle of the weapon.

In the first step, we will randomly pick the value of [xi] and we can check whether simulated values of terminal velocity in the first experiment and balancing force in the second experiment correspond to the theoretical values.
Moreover, because of the low velocity of the pounder when entering the water, pinch-off occurs in less time and at lower depths, and its velocity increases after pinch-off until it reaches terminal velocity. Increases in pounder drop heights increase water entry velocity.
[U'.sub.r] = radial terminal velocity of particle relative to gas, m
The vertical radial velocity [V.sub.r] includes the vertical air motion plus the reflectivity-weighted terminal velocity of the ensemble of particles within the pulse volume.
From Viet-Flakes, 1965, and Snows, 1967, which protested the Vietnam War, to the "Lebanon Series," 1983-91, on the destruction of Beirut, and Terminal Velocity, 2001-2005, wherein she took on 9/11, she has long borne witness to cruelty and empathy, though discussions of her oeuvre sideline this theme in favor of other, related issues of gender and sexuality.
For no power return vehicle, its terminal velocity should be less than 7800 m/s.
"I saw Kittel had reached his terminal velocity and I knew I still had something left," said the Manxman.
If measurements of the oil drop's velocity were made while the drop was at terminal velocity, the net force would be reduced to zero during all measurements--allowing for the determination of the drop's radius.
Its subsidiaries include Generation Orbit, Terminal Velocity and Blink Astro.
To address this technical challenge, we have considered various methods, such as designing several groups of nominal trajectories offline and selecting an appropriate trajectory online to conduct the whole-phase tracking guidance based on the estimated terminal velocity and tracking the nominal trajectory in the first stage of launch vehicle and then tracking online generated trajectory after applying open-loop energy management in the second stage to achieve terminal constraint.
While manufacturers usually report throws to 50 fpm (0.25 m/s) in their catalogs, in selection software the desired terminal velocity is usually a selectable parameter.
