Rotating propeller soliton

Nonlinear Guided Waves and Their Applications, 2001
We demonstrate experimentally and theoretically (both analytically and numerically) a new type of spatial soliton: a rotating "propeller" soliton. This is a composite soliton made of a rotating dipole component jointly trapped with a bell-shaped component. We observe as much as 239 degrees of rotation over 13 mm of propagation (6.5 diffraction lengths).

Preparation of high self-healing efficient crosslink HTPB adhesive for improving debonding of propellant interface

, 2020
The problem of debonding the interface between propellant grain and propellant coating has been a tricky problem that has puzzled many scholars. Self-healing adhesives are expected to solve this problem.

Propeller Injuries

Southern Medical Journal, 1976
Water skiing, boat racing, skin and scuba diving, and pleasure boat cruising are increasing in popularity. As a result the incidence of injuries secondary to motor propellers is becoming more frequent. In a ten-year period from 1963 to 1973, I collected a total of nine cases.

Effect of aluminum nanoparticles on rheological behavior of HTPB-based composite rocket propellant

Journal of Energetic Materials, 2018
The aim of this article was to understand the rheology of composite propellant containing aluminum nanoparticles, as it is a highly filled mixture of solids and is difficult to process. Aluminum nanoparticles utilized as a filler were characterized using
