Escalating Engine Repair Costs Jeopardize Engine Performance

The airfoils on a gas turbine engine are subjected to many abuses, including dust and debris, and even birds, which are sucked into the engine at high speeds. Studies show that regular inspection and repair of these airfoils enhance engine performance. See the H&L Instruments Airfoil Contour Control Application Note to read about the benefits gained from correctly contoured fan blades.

The Model 900C/CE Edge Profile Comparator™ is a precision instrument used for inspecting the leading and trailing edges of aircraft turbine fan blades. The instrument can also inspect stationary steam and gas turbine engines used to produce electric power. The Model 900C/CE contains an optical module that employs a solid state video camera and an infrared light source for illuminating the blade edge. The blade edge is magnified 20x or 40x, dependent on the option purchased.

The Model 900C/CE is compatible with inspection of a range of turbine engine blades including:

General Electric CF6-6, CF6-50, CF6-80, CF34, GE90, GEnx, J79, and TF39 (USAF C5-A)
CFM International CFM56
Rolls Royce Trent 800, 900, 1000, XWB, RB211, and TF41
