Minimum-Time Roll Around the Velocity-Vector Maneuver of Aircraft

In this paper, some results are provided for minimum time roll about velocity vector maneuvering with thrust-vectoring and aerodynamic control in effect. The mathematical model for attitude motions of the aircraft is developed. First order necessary conditions for optimality using Pontryagen principle is applied, and the existence of an extreme family of solutions for the maneuver is shown. Mul...

Geomagnetic activity and wind velocity during the Maunder minimum

Following a given classi®cation of geomagnetic activity, we obtained aa index values for the Maunder minimum (1645±1715). It is found that the recurrent and ̄uctuating activities were not appreciable and that the shock activity levels were very low. The aa index level was due almost entirely to the quiet days. Calculated average solar-wind velocities were 194.3 km s from 1657 to 1700 and 218.7 ...

Minimum Velocity Dispersion in Stable Stellar Disks . ̧ Numerical Simulations

We used N-body dynamical simulations to analyze the conditions for the gravitational stability of a three-dimensional stellar disk in the grav-itational field of two rigid spherical components — a bulge and a halo, whose central concentrations and relative masses vary over wide ranges. The number of point masses N in the simulations varied from 40 to 500 thousands and the evolution of the simul...

Constraints on Minimum Velocity Variance for Seismic Traveltime Tomography

SUMMARY Traveltime data together with known spacing between sources and receivers for seismic transmission tomography can be used to determine rigorous constraints on the minimum and maximum wave speeds in the propagating medium. These constraints lead to a new minimum variance criterion on inversion algorithms. These results do not improve the velocity reconstructions directly , but provide ri...
