CodeXplain on Instagram: "A jam jar pulsejet engine is a simple yet fascinating demonstration of reactive propulsion. It works by igniting a fuel-air mixture inside a jar, usually methanol vapor mixed with air, which rapidly combusts and expands. The expanding gases rush out of the opening, creating thrust, while the sudden drop in pressure draws fresh air and fuel back in to repeat the cycle. This repeating cycle of ignition and refill happens many times per second, producing the distinctive pu

HOMEMADE_MACHINE.00ka on Instagram: "homemade jet engine, often referred to as a pulsejet or a small turbojet constructed from repurposed parts (like an old turbocharger), is a device that generates thrust by rapidly expelling a high-velocity stream of hot gas. Key features and considerations include: Design & Principle: These projects typically operate on the Brayton cycle (for turbojets) or a simpler valveless or valved combustion system (for pulsejets). Pulsejets are simpler, using resonant c
