Abstract
An aircraft engine hazard zone projection system is described that includes an engine having an engine inlet and an engine outlet, and engine housing, and a light-emitting system connected to the engine housing. The light-emitting system is configured to project light on a ground below the engine housing so as to form at least one predetermined hazard zone surrounding the engine. The at least one predetermined hazard zone identifies at least one of an area subject to an engine inlet suction force or an area subject to an engine outlet exhaust force.
Claims20
An aircraft engine hazard zone projection system, the system comprising:
- an engine having an engine inlet and an engine outlet;
- an engine housing;
- and
- a light-emitting system connected to the engine housing and configured to project light on a ground below the engine housing so as to form at least one predetermined hazard zone surrounding the engine, wherein the at least one predetermined hazard zone identifies at least one of an area subject to an engine inlet suction force or an area subject to an engine outlet exhaust force, wherein the light-emitting system is mounted on an underside of the engine housing and comprises an emitter and an emitter window, wherein the emitter window protrudes from the engine housing, and wherein a shape of the emitter window comprises a tear-drop shape.
An aircraft engine hazard zone projection system, the system comprising:
- an engine housing;
- and
- a light-emitting system connected to the engine housing, wherein the light-emitting system is configured to project light on a surface below the engine housing so as to form a predetermined hazard zone surrounding the engine housing, wherein the light-emitting system is mounted on an underside of the engine housing and comprises an emitter and an emitter window, wherein the emitter window protrudes from the engine housing, and wherein a shape of the emitter window comprises a tear-drop shape.
A method for visually representing a hazard zone surrounding an aircraft engine, the method comprising:
- defining a hazard zone comprising an area subject to an engine inlet suction force of the aircraft engine or an engine outlet exhaust force of the aircraft engine;
- projecting a visible-light boundary of the hazard zone on a surface below the aircraft engine;
- and
- attaching a light-emitting system to an underside of an engine housing of the aircraft engine, wherein the light-emitting system is configured to project the visible-light boundary of the hazard zone on the surface below the aircraft engine, wherein the light-emitting system comprises an emitter and an emitter window, wherein the emitter window protrudes from the engine housing, and wherein a shape of the emitter window comprises a tear-drop shape.
