ABSTRACT:
An apparatus is disclosed for temporarily attaching a pre-atomization bowl to a wall of a generally annular combustion chamber during assembly of the combustion chamber with the fuel injector assembly. The attachment apparatus holds each of the pre-atomization bowls in a position so as to minimize the stress imparted to the fuel injectors during assembly of the engine components. The apparatus utilizes a magnetic attachment device to hold the pre-atomization bowls in their assembly positions. The force of the magnetic attachment device is sufficient to hold the pre-atomization bowls in these positions against the effect of gravity, but is insufficient to prevent the radial movement of the pre-atomization bowls relative to the combustion chamber once the turbojet engine has been assembled. Thus, the device does not inhibit the radial play of the pre-atomization bowls once the engine has been asssembled.
