Benefits of technology

[0013]In yet another advantageous embodiment, a method for shot peening may be present. A stream of shot may be directed into an inlet of a nozzle. The stream of shot may be directed into a first channel in an inlet of a nozzle. The stream of shot may be directed into a second channel in the inlet. The second channel may be smaller than the first channel. The stream of shot may be redirected to form a plurality of

Problems solved by technology

Manually performing shot peening may be laborious and time-consuming.
With a lower amount of air pressure, the amount of shot media that can be introduced into the air stream is limited, and the time needed to perform shot peening is greater than with a higher air pressure.

Embodiment Construction

[0027]Referring more particularly to the drawings, embodiments of the disclosure may be described in the context of aircraft manufacturing and service method 100 as shown in FIG. 1 and an aircraft 102 as shown in FIG. 2. During pre-production, aircraft manufacturing and service method 100 may include specification and design 104 of aircraft 102 and material procurement 106.

[0028]During production, component and subassembly manufacturing 108 and system integration 110 of aircraft 102 takes place. Thereafter, aircraft 102 may go through certification and delivery 112 in order to be placed in service 114. While in service by a customer, aircraft 102 may be scheduled for routine maintenance and service 116 (which may also include modification, reconfiguration, refurbishment, and so on).

[0029]Each of the processes of aircraft manufacturing and service method 100 may be performed or carried out by a system integrator, a third party, and / or an operator (e.g., a customer). For the purposes ...

Abstract

A method may be present for sending shot onto a surface. A stream of shot may be directed into an inlet of a nozzle. The stream of shot may be redirected to form a plurality of streams of shot within the nozzle. The plurality of streams of shot may be directed out of a plurality of outputs of the nozzle.

Description

BACKGROUND INFORMATION[0001]1. Field:[0002]The present disclosure relates generally to manufacturing and in particular to a method and apparatus for processing metal components. Still more particularly, the present disclosure relates to a method and apparatus for performing shot peening on of metal components.[0003]2. Background:[0004]In manufacturing various components, it may be desirable to improve the properties of the material. One process that may be performed on a metal material may be peening. Peening may be a process of working a surface of a metal to change the properties of the metal. Typically, the change may be an improvement to the properties of the metal. Peening may be performed using a mechanical means such as, for example, without limitation, blows by a hammer, shot peening, and laser peening.[0005]With shot peening, a surface of a metal material may be impacted with shot to produce a compressive residual stress layer and modify mechanical properties of the metal. ...
