Method and apparatus to protect downstream engine components from damage in the event of a turbine failure

An apparatus to protect downstream engine components from damage in the event of a turbo failure, comprising:

• an outer body having an inlet opening at a first end of a first diameter, an outlet opening, and an interior of a second diameter which is larger than the inlet opening;
• an inner body extending into the interior of the outer body with air flow openings in the inner body communicating with the outlet opening;
• and
• an impaction plate supported by the inner body, the impaction plate being in axial alignment with the inlet opening, such that upon failure of the turbo, turbo fragments strike and are slowed by impact with the impaction plate, the turbo fragments collecting in the interior of the outer body with air escaping by entering the air flow openings of the inner body and passing to the outlet opening.

An apparatus to protect downstream engine components from damage in the event of a turbine failure, comprising:

• an outer body having a first end, a second end and a peripheral sidewall, an inlet opening at the first end of a first diameter, an outlet opening at the second end;
• and an interior of a second diameter which is larger than the inlet opening;
• a hollow inner body having a first end, a second end and a peripheral sidewall that defines an interior air flow passage, the second end of the inner body communicating with the outlet opening of the outer body and the first end of the inner body extending into the interior of the outer body in axial alignment with the inlet opening to define a debris collection annulus, air flow openings in the peripheral sidewall of the inner body communicating with the interior air flow passage;
• and
• an impaction plate at the first end of the inner body, such that upon failure of the turbo, turbo fragments strike and are slowed by impact with the impaction plate, the turbo fragments collecting in the debris collection annulus with air escaping the debris collection annulus by entering the air flow openings in the peripheral sidewall of the inner body and passing along the interior air flow passage to the outlet opening.

A method of protecting downstream engine components from damage in the event of a turbine failure, comprising:

• positioning a debris trap downstream of a turbo and upstream of an engine component, the debris trap comprising:
• an outer body having an inlet opening at a first end of a first diameter, an outlet opening, and an interior of a second diameter which is larger than the inlet opening;
• an inner body extending into the interior of the outer body with air flow openings in the inner body communicating with the outlet opening;
• and
• an impaction plate supported by the inner body, the impaction plate being in axial alignment with the inlet opening, such that upon failure of the turbo, turbo fragments strike and are slowed by impact with the impaction plate, the turbo fragments collecting in the interior of the outer body with air escaping by entering the air flow openings of the inner body and passing to the outlet opening.
