Gas Turbine / Turbojet Engine Cutaway Model — Axial Flow Compressor, Combustion Chamber, Turbine, 17"
Gas Turbine / Turbojet Engine Cutaway Model — Axial Flow Compressor, Combustion Chamber, Turbine, 17"
Couldn't load pickup availability
Cutaway sectional teaching model of a gas turbine / turbojet jet engine — light-and-strong metal construction reveals every stage of jet propulsion: air intake, 2-stage axial-flow compressor, fuel supply, combustion chamber, turbine rotor, jet thrust nozzle, and exhaust. Printed schematic diagram on the base labels each component + shows the Brayton cycle (isobaric combustion + isentropic compression/expansion). 17" long × 6" high — desktop demonstration size. For aerospace engineering, mechanical engineering, physics, and STEM education. $599.99 direct.
Components visible (in flow order)
- Air intake — cowl showing airflow direction into compressor
- Axial flow compressor (Stage 1) — rotor + stator blades compressing incoming air ~4-8× ambient pressure
- Axial flow compressor (Stage 2) — second stage compressing to ~15-30× ambient (typical turbojet)
- Fuel supply line — kerosene / JP-4 injection into combustion chamber
- Combustion chamber — continuous combustion of compressed air + fuel at ~1500°C
- Turbine rotor — expanding hot gas drives turbine that powers the compressor via central shaft
- Jet thrust nozzle — remaining hot gas exits at high velocity, creating thrust
- Exhaust — reduced pressure/temperature exit to atmosphere
Teaching applications
- Aerospace engineering — jet propulsion, gas turbine theory, Brayton cycle
- Mechanical engineering — turbomachinery, compressor + turbine design
- Thermodynamics — Brayton cycle analysis, isobaric/isentropic processes
- Fluid mechanics — compressible flow, choked nozzle, subsonic + supersonic transitions
- Power engineering — gas turbine power generation (industrial + utility)
- Aviation training — pilot ground school + AMT (Aircraft Maintenance Technician) training
- Aerospace museums + displays

FAQ
Does this actually run?
No — this is a STATIC CUTAWAY MODEL for teaching, not a functional jet engine. Students see all internal components (compressor blades, combustion chamber, turbine, nozzle) in their spatial relationship + flow order. For running gas turbine demos, look at industrial "cutaway trainers" ($15K+).
What can students learn from a static model?
Brayton cycle analysis (temperatures + pressures at each station 1→5), spatial relationships (why the turbine is downstream of combustion, how it drives the compressor via shaft), component identification (blade rows in axial compressor + turbine, combustion chamber geometry), and flow-path visualization (air enters cool + slow, exits hot + fast).
Is this a real jet engine cutaway or a teaching representation?
Teaching representation — proportions + component visibility are optimized for education, not exact scale of a real engine. For real cutaway engines (retired GE / P&W / Rolls-Royce engines cut open), aerospace museums + military bases sometimes have those but they're not commercial equipment.
