A rotating spring-loaded latch replaces wear-prone wedge retention, keeping turbine blades secure during grit blasting and extending tool life.

Real-time capacitance sensing tracks die closure and alignment to cut forging setup time, waste, and dimensional variability.

Integral front and rear vane sections use shaped limiting lines and cutting steps to control gap and overlap for better turbine aerodynamics.

Damaged engine case tabs are cut out and replaced with a new flange section, avoiding full case scrapping while preserving structural integrity.

Chevron-shaped cooling holes keep coolant attached to hot gas turbine surfaces longer, improving film cooling with less flow separation.

A 3D woven CMC platform bonded to the airfoil and root cuts interlaminar and root bending stresses in turbine blades.

A platform breakout opening forms internal connecting passages for turbine airfoil cooling without drilling external walls, preserving strength.

A single bonding-tool cure co-cures the composite spar and bonds the skin, cutting assembly time, cost, and void-related defects.

A layered elastomeric airfoil coating enables hand-sanded field repair, avoids chemical stripping, and preserves erosion protection.

Access-port repair stops gas turbine cracks in place using guided local heating, avoiding engine removal and cutting maintenance downtime.

Localized induction tempering relieves stress in turbine nozzle partitions on site, avoiding disassembly, transport delays, and furnace heating.

Selective machining and weld cladding rebuild worn diaphragm rails to nominal dimensions, reducing material waste, downtime, and full replacement.

A two-stage forging route with drilling, ring rolling, and inclined second forging cuts dead metal regions while improving ring strength.

Capacitive sensors track die gap and alignment in real time, helping forging presses cut setup time, waste, and dimensional variation.

Core-defined reference points align cast hollow workpieces to machine internal cavities accurately despite sacrificial core placement variation.

A relief cut redirects stress away from cracked turbomachine repair zones, enabling sealed filler repairs in hard-to-weld superalloys.

A recessed membrane layout evens forming pressure in superplastic turbomachine blades, preventing sticking, arched webs, and scrap.

Cold spray rebuilds worn turbine engine alloy regions while preserving metallurgical microstructure and maintaining repair deposit properties.

Split vane arc segments are inserted radially between rotor blade rows to avoid assembly interference while maintaining sealing and alignment.

A ceramic protective crown at the blade tip shields CMC airfoils from blade-track rub and environmental exposure, improving turbine blade durability.

An integral blade socket and optimized transition radius strengthen rotor-to-hub or shroud bonds, reducing stress at higher rotational speeds.

A relief cut redirects tensile stress so brazed or welded filler can seal cracked turbine components without carrying full tension loads.

A burnished aluminum-silicate repair coating restores damaged corrosion-resistant surfaces without identifying the original chromate coating.

Dispersed chromium-silicon oxides in a laser-overlaid cobalt coating improve sliding-part wear resistance below 600°C.

Centrifugal casting plus 1045-1255°C heat treatment cuts porosity and equipment complexity while preserving turbine-blade alloy properties.

Pressurized internal channels and heated inert gas shape hollow turbine airfoils to precise contours while reducing wall thickness and weight.

Hybrid CMC and metal airfoil assemblies use transient liquid phase bonding to achieve complex turbine geometries with strong joints.

Microwave sintering and directed energy fusion create versatile powder coatings that improve gas turbine component wear resistance at lower cost.

Localized laser or plasma deposition rebuilds worn guide vane mounting hooks around the housing circumference while limiting distortion and restoring wear resistance.

A larger rotor blade ring is moved to a new axial position in the conical housing to raise turbine output without changing the housing.

An alumina-siloxane slurry with carbon fibers forms porous, strong ceramic cores that resist reactive metals in complex investment casting.

Front access with a toothed tubular wrench and rotor lock removes a seized HP rotor link nut without cutting it or contaminating IGB gearing.

A gas turbine vane repair insert uses axial sliding guides to replace damaged trailing-edge sections with simpler, more precise alignment.
