Scaling of hypervelocity impact craters in ice with impact angle [PDF]
Journal of Geophysical Research: Planets, 2002 Hypervelocity oblique impacts using spherical 1 mm diameter aluminum projectiles at velocities of (5.2 ± 0.2) km s−1 were incident at angles ranging from normal (0° to the vertical) to grazing incidence (80°) onto thick polycrystalline H2O ice targets at 253 K. Data were obtained to distinguish changes in crater size and shape.

Variation in sprinkler irrigation droplet impact angle on the physical crusting properties of soils
Agricultural Water Management, 2023 The angle at which a droplet impacts determines its shearing and compaction effects on soil, which in turn affects the formation and properties of the physical soil crust.

Three-Dimensional Fast Fixed-time Convergence Guidance Law With Impact Angle Constraint
IEEE Access, 2019 In this paper, a three-dimensional (3D) impact-angle-control guidance law is proposed based on the approaches of nonsingular terminal sliding mode control and fixed-time convergence theory to intercept a maneuvering target.

Impact-Angle-Control Guidance Law with Terminal Constraints on Curvature of Trajectory
Mathematics, 2023 This paper presents an impact-angle-control guidance law with terminal constraints on the curvature of the missile trajectory. The formulation takes into account nonlinear kinematics and time-varying velocity, allowing for more general cases in which the

The Impact of a Body on a Water Surface at an Arbitrary Angle [PDF]
Journal of Applied Physics, 1950 This paper presents an approximate method of determining the pressure distribution during impact on the surface of a body which strikes a horizontal water surface at an arbitrary angle. The effect of the splash is neglected and the pressure on the free boundary is assumed proportional to the potential, as if the process were an impulse ...

Blast Fragment Impact of Angle-Ply Composite Structures for Buildings Wall Protection
Buildings, 2023 This paper investigates the fragment performance of several composite panels for attaching to the inside walls of a building structure. These panels were developed using different types of fiber woven fabrics (W0, W90) combined with distinct layers ...

Finite Time Guidance Law to Intercept Desired LOS Angle Using NTSM Control [PDF]
فصلنامه علوم و فناوری فضایی, 2018 Nonsingular terminal sliding mode (NTSM) guidance for intercepting the desired line of sight (LOS) angle in terminal phase is proposed in this paper. In order to satisfy the predefined LOS angle and to intercep into target, a nonsingular terminal sliding
