These remarkable systems are a marvel of engineering, designed to ensure pilot survival at incredible speeds and under extreme conditions. Let’s dive into the fascinating mechanics behind them! 🚀 🛠️ Key Components and How They Work: High-Speed Ejection: 💨 Ejection seats are built to safely propel pilots out of the aircraft at jaw-dropping speeds—from 0 to 600 knots (that’s up to 1,111 km/h!). Parachute Deployment: 🪂 After ejection, each seat deploys a parachute to guarantee a safe landing, ensuring the pilot can descend gently back to Earth. Pyrotechnic Magic: 💥 The entire ejection process is kicked off by a pyrotechnic mechanism. This system uses Cartridge Actuated Devices (CAD) and Propellant Actuated Devices (PAD) to perform key tasks like canopy jettison, seat ejection, and parachute release. Rigorous Testing: 🧪 Before they ever see use, ejection seats undergo intense testing, including 22 sled tests at varying speeds and pilot weights, to confirm their safety and reliability. 🚀 Advanced Features: Next-Level Safety Zero-Zero Capability: Modern seats, like the ACES II, can safely eject a pilot from a stationary aircraft on the ground. 💺✨ Using small rockets, these seats launch upward, providing enough height for the parachute to deploy even when the aircraft is at zero altitude and zero speed. Complex Systems: Ejection seats are intricate, with up to 20 different systems and subsystems working in harmony. This includes sequencing mechanisms, drogue parachutes, and under-seat rocket motors, all focused on ensuring pilot safety. Ongoing Maintenance: 🛠️ Regular upkeep is essential to ensure these life-saving systems stay in top shape. Ejection seats need thorough inspections every 36 months, with constant monitoring via Time Compliance Technical Orders (TCTO) to address any wear and tear. 🚨 The Critical Role of Maintenance Maintenance isn’t just a best practice—it’s life-saving. These seats endure extreme G-forces, intense stress, and harsh environments. Failing to maintain them to the manufacturer’s guidelines can put pilots at serious risk. ✈️ Why Ejection Seats Matter The engineering behind ejection seats is as awe-inspiring as it is crucial for air safety. With complex mechanisms and rigorous testing, these systems are a pilot’s last line of defense in an emergency. Ejection seats aren’t just technology—they’re life-savers in the truest sense! 💥✈️ "Credits: 🌟 All write-up is done by me(P.S.Mahesh) after indepth research.

As the aerial agricultural spraying season is about to start here it was such a superb opportunity to conduct another turbine startup current measurement and characterization project. 👨💻 Listen to to this mighty 690sHp Walter M601 turboprop engine roaring to life and breaking the silence at a calm airfield! 😎 The Walter M601 is a turboprop aircraft engine produced by Walter Aircraft Engines of the Czech Republic and pretty similar to the Pratt & Whitney Canada PT6 series in layout, size and power rating. The engine is equipped with a 5-terminal 4-pole starter-generator capable of a continuous output of 200A at 28V. ⚡ Diving into the unknown! Based on my calculations i estimated a peak inrush current of around ~720Apk on startup, therefore a 24V GPU pack made of very high performance SLA AGM batteries with a total internal resistance of 9 milliohms has been used. Surprise was the moderate peak inrush current which has not even reached 500Apk mark. On the video all related parameters are shown that is required to design a Experimental onboard battery pack for this aircraft. ✈ 🔋 #aviation #turboprop #aircraftbattery #engineering #enginestart #turbineengine

 Pratt & Whitney PW1100G-JM model, part of the Geared Turbofan (GTF) Model The PW1100G-JM's issues are largely a result of the ambitious design goals set by Pratt & Whitney to achieve fuel efficiency, reduced emissions, and lower operating costs. However, these goals have pushed the limits of current materials science and mechanical engineering capabilities. The engine's design innovations, like the geared turbofan mechanism, introduce additional complexity, making it difficult to achieve the same level of reliability seen in older, simpler engines. #trending #aviationlovers #flighttraining #avgeek #aviationdaily #aviation #simulator #FlightSimulator #flying #Flight #Aviation #avgeek #aviationlovers #aviationnews #aviationdaily #flights #travel #pilottraining

Preparing for Failure: Food for thought for any business As shown here, many folks are unaware of all that goes into minimizing human loss in the event of system failure in a helicopter, particularly the powerplant. In reality, autorotation is an important part of pilot and crew training. Understanding that in many cases, adjustments to the collective and some pedal input can shift the airflow dynamics turning the still rotating blades into a "parachute" of sorts. The key to success in a live situation is practice, practice, and more practice. When a crew has experienced this in practice, they're more inclined to keep a cool head about them so they can navigate to safety and provide effective communication. Of course, preventive maintenance and equipment checks are key to preventing (most) failure in the first place. My question here: What does your company do to prepare for failure of systems and processes? Maybe even more, what do you do to try to prevent it? Here's a previous post with a video that shows the pilot's actions to induce autorotation for a safe landing. https://lnkd.in/emMvtmrU I'm sure Mr. Tyson doesn't mind being proven wrong, he is a scientist who by definition typically encounters more failures than success in their explorations.

ROV Design 101 - Thruster selection Thrusters are to an ROV what Jet Engines are to a 747. The ROV needs the right number and specs to operate properly. Here are 10 rules ("more like guidelines") for selecting the appropriate thrusters. This assumes we are purchasing off the shelf electric thrusters: 1. It is a process of elimination and no one unit will work perfectly. 2. 500 Newtons of thruster per 1 square meter ROV cross sectional area is a good starting point. 3. Brushless thruster motors with "sensorless" controllers are generally best, but they require a good "motor controller" or Electronic Speed Controller (ESC) to operate. 4. Select thruster/controller combination for the power system available. 12V, 24V, and 48V will be most common for small ROVs. 5. Account for maximum thruster/controller current. 8 X 40A = is enough power to start a truck and melt large conductors. 6. Larger and slower propellers (props) are nearly always more efficient. 7. "Power Management" by limiting either maximum command, adjusting voltage, or be prepared to handle max power X number of thrusters. 8. Maintain cooling - do not bunch up high current cables inside a small enclosed space. Use good water flow. 9. Select a control method easy to implement. Analog voltage (0-10V for instance), Pulse width modulation (PWM), RS485, and CANBUS are all common. 10. Pay attention to connectors and cable length. Cables should be run cleanly and well secured, and connectors should make the thrusters easy to change, as they sometimes need to be replaced. Bonus - Pay attentional to propeller direction of rotation. The torque generated is not insignificant and this can be counteracted by balancing torques from different motors (i.e. half clock-wise and half anti-clockwise). #PoseidonROV #OceanExploration #ROV #Engineering #OffshoreWind

The fundamental design such as thrusters and orientation builds a strong ROV platform.

A good explanation of what autorotation is in a helicopter when engine power is lost.
