Aircraft Power Plant Components TRIZ Cases

A curved pylon protrusion reshapes pressure near the nacelle boattail to keep airflow attached, cutting drag, noise, and structural stress.

Hinged rods, springs, and locators let a mast fairing track nacelle cowl motion to limit drag, vibration, and stress during thrust reversal.

Adjustable inlet cowl droop responds to crosswind and wind shear to prevent intake flow separation while preserving low-drag turbine operation.

A shaped pylon fairing shifts inboard surface geometry to cut drag and shock-induced separation on wing-mounted engines.

A two-part secondary lateral fairing lets the aircraft cowl open beyond 65° for better equipment access while preserving aerodynamic continuity.

Internal hook-mounted partitions split each cell into two resonators, cutting aircraft acoustic absorber weight while enabling independent tuning.

Internal partitions split honeycomb cells into two resonator types, widening aircraft sound attenuation while avoiding added mass and assembly complexity.

A spring-biased lever and catch lock keeps an aircraft cowl latch handle secured against vibration-induced unlocking.

A roughened turbulator on the nacelle inlet inner surface forces laminar-to-turbulent flow transition to improve heat transfer and cool downstream sections.

A roughened turbulator on the nacelle inlet inner surface triggers local turbulence to improve heat transfer and lower adjacent structure temperature.

An ergonomic hook latch uses interlocking handles to improve operator access while securing aircraft nacelle covers.

Rotating and translating links coordinate hook engagement across cowl doors, reducing component count and supporting secure closure during flight.

One-piece plenum panels with pre-installed adhesive fasteners attach to nacelle skins, helping sustain laminar airflow and reduce drag.
