Three-dimensional printing of continuous-fiber composites by in-nozzle impregnation

open access: yesScientific Reports, 2016
We have developed a method for the three-dimensional (3D) printing of continuous fiber-reinforced thermoplastics based on fused-deposition modeling. The technique enables direct 3D fabrication without the use of molds and may become the standard next ...

Coverage and drift potential associated with nozzle and speed selection for herbicide applications using an unmanned aerial sprayer

Weed technology, 2019
In recent years, unmanned aerial vehicle (UAV) technology has expanded to include UAV sprayers capable of applying pesticides. Very little research has been conducted to optimize application parameters and measure the potential of off-target movement ...

Nozzle external geometry as a boundary condition for the azimuthal mode selection in an impinging underexpanded jet

Journal of Fluid Mechanics, 2019
The role of the external boundary conditions of the nozzle surface on the azimuthal mode selection of impinging supersonic jets is demonstrated for the first time.

Advanced Rocket Nozzles

Journal of Propulsion and Power, 1998
Several nozzle concepts that promise a gain in performance over existing conventional nozzles are discussed in this paper. It is shown that signie cant performance gains result from the adaptation of the exhaust e ow to the ambient pressure. Special attention is then given to altitude-adaptive nozzle concepts, which have recently received new interest ...
