Working Principle of the Turboprop Engine (Example : PT6 Engine) __________________||||________________||||________________ محرك turboprop من نوع PT6 يُعد من أكثر المحركات استخداماً في الطائرات الصغيرة والمتوسطة. يعتمد في عمله على مبدأ gas turbine لكن مع توجيه أغلب الطاقة لتدوير propeller بدلاً من توليد دفع نفاث. 1. Air Intake (مدخل الهواء): يدخل الهواء من الجزء الخلفي للمحرك عبر reverse-flow intake system، وهي ميزة فريدة في محرك PT6، حيث يدخل الهواء من الخلف ويمر للأمام داخل غرف الضغط والاحتراق. 2. Compressor Section (قسم الضاغط): يتكوّن من axial compressor stages تليها centrifugal compressor. هذه المجموعة تضغط الهواء إلى ضغط مرتفع قبل دخوله غرفة الاحتراق. 3. Combustion Chamber (غرفة الاحتراق): يتم خلط الهواء المضغوط مع الوقود داخل combustion chamber، ويُشعل المزيج لتوليد غازات عالية الحرارة والطاقة. 4. Turbine Section (قسم التوربين): الغازات الساخنة تمر عبر مرحلتين من التوربين: • Gas generator turbine: تدير الضاغط فقط. • Power turbine: غير متصلة ميكانيكياً بالضاغط، وتقوم بتدوير reduction gearbox الذي يحرك propeller. 5. Reduction Gearbox (علبة تخفيض السرعة): تقوم هذه العلبة بتقليل سرعة دوران التوربين العالي (حوالي 30,000 rpm) إلى سرعة مناسبة لتشغيل propeller (حوالي 2,000 rpm). 6. Exhaust (العادم): يُطرد الغاز المتبقي من الخلف، مولداً نسبة صغيرة من الدفع (حوالي 10–15%). 7. Propeller Thrust (دفع المروحة): الجزء الأكبر من الطاقة (80–90%) يُستخدم لتدوير propeller، وهو ما ينتج القوة الدافعة الرئيسية للطائرة. ملخص: • نوع المحرك: Free-turbine reverse-flow turboprop. • نسبة الدفع من المروحة: ≈ 85%. • أهم ميزة: تصميم reverse-flow الذي يجعل المحرك قصيراً وسهل الصيانة

SCREW COMPRESSOR ASSEMBLY 🔧⚙️

Pratt & Whitney J57 Turbojet The J57 turbojet was the first production jet engine to produce 10,000 pounds of thrust. The J57 featured a dual-rotor axial-flow compressor, which lowered fuel consumption over a wide operating range and improved the sluggish acceleration characteristic of previous jet engines. J57 production began in 1953. The same year, Pratt & Whitney was awarded America's highest aviation honor, the Collier Trophy, for the design and development of the J57. When production ended in 1970, Pratt & Whitney had built more than 21,000 engines. The museum's cut-away engine is a YJ57-P-3, the first version to go into production. Rated at only 8,700 pounds of thrust, it served as a prototype for higher-powered engines used in operational B-52s. Later versions of the J57 and its commercial equivalent, the JT3, were improved to reach 18,000 pounds of thrust with afterburner. In addition to the B-52, the J57 powered numerous USAF aircraft, including the KC-135, F-100, F-101, and F-102. #engine #avgeek #dronevideo

A main air compressor is a crucial piece of equipment, especially on ships, that compresses atmospheric air to very high pressures (typically 30 bar) to start large engines. These systems store the compressed air in a receiver tank and also supply it at lower pressures for general services, like control systems. A main air compressor system includes components like a motor, a compression element, an air receiver, and various valves and filters to ensure the air is clean, dry, and delivered at the correct pressure.
