Definitions

  • the present invention is applied in the formation of turbine hulls due to their high dimensional accuracy but the manufacturing process.
  • the present invention relates generally to a high precision manufacturing method and tooling and dimensional control of the containment hull of a turbine used in aircraft.
  • the turbines used in these devices have a fan and multiple fan blades arranged to rotate around a central axis. Catastrophic damage can occur to the aircraft and its occupants in case a broken fan blade is driven radially outward from the axis of rotation by force and impacts on the centrifuge of fuselage aircraft. To avoid these damages, it is common to include a generally cylindrical hull on the periphery to contain the fan blades. For engines of smaller diameter, adequate containment capability can be achieved with a simple metallic hull, thick enough to resist torque ⁇ penetration blade fragments. However, for larger diameter motors, a metal case thick enough to resist penetration is virtually impossible because of the weight that this implies. Moreover, these helmets have complicated geometries that demand very high precision and dimensional control.
  • the soft wall helmets use lightweight, high-strength, multi-layered structures around the structure.
  • a fragment of the turbine blade or blade will penetrate the support structure locally and strike but will not cut the fabric.
  • the tissue layers capture and contain the fragment.
  • Conventional support structures can be made of aluminum for weight considerations.
  • the support structure may include aluminum honeycomb structures.
  • US Pat. No. 0 6,053,696 proposes a composite material hull for the turbine.
  • the shell or composite shell includes two support rings structurally attached to a central portion that has an open lattice structure.
  • Other examples of fiber reinforced composite structures and manufacturing methods are provided in the following US patents.
  • UU. USA Pat. No. 0 4,086,378 to Kam et al.
  • Figure 1 Array of ultrasound sensors on the surface of the helmet and infrared cameras
  • the present invention describes a novel tool and method of manufacture of turbine hull for aircraft characterized by the following steps: Receive the specifications and dimensional tolerances corresponding to the characteristics required for a turbine hull of an aircraft: the selection of a wind capture of the design of the turbine case profile in accordance with the characteristics data received; the design, manufacture and validation of a structural support piece (1) whose external contact profile with said helmet (2) coincides with its internal surface with tolerance less than 1 thousandth of an inch; placing said mold (1) inside the structure of the hull of the turbine to be molded; placement of at least 6 vibration actuators (3) on the outer surface of the turbine hull; Capture video images per camera with at least three infrared sensor arrays (4) separated 120 degrees from each other; temperature uniformity analysis of thermal images per computer unit (5); evolution analysis of mechanical stress points;
