21 Gas Turbines Reverse Thrust📄 Detailed Notes⚡ Cheat Sheet Results📄 Notes ⚡ Cheat Sheet📄 Notes ⚡ Cheat SheetQ1. The thrust reversers of jet engines may use clamshell doors in order to: change the direction of the exhaust gas stream stop the flow of the exhaust gas stream reduce the pressure of the exhaust gas stream by diffusing it to atmosphere absorb any surge in engine thrust Q2. Most high-bypass (unmixed) turbofan engines are equipped with a cold exhaust reverser (fan reverser) only in order to: reduce the risk of exhaust gas re-ingestion. prevent disturbance of cold exhaust reversed airflow by the hot exhaust reversed gas flow. save costs and mass at the expense of a reduction in available reverse thrust. prevent extra fuel consumption due to operation of the hot exhaust reverser (turbine reverser). Q3. To achieve reverse thrust on a turbine engine with a high by-pass ratio, generally: the fan is stopped the flow of hot stream air is reversed the fan flow is deflected the direction of rotation of the fan is reversed Q4. On most high by-pass ratio (fan) engine, reverse thrust is achieved by reversing: only the direction of the exhaust gas flow the direction of rotation of the fan the direction of both the exhaust gas flow (hot stream) and the fan airflow (cold stream) only the direction of the fan airflow Previous Submit The Test← Previous QuizNext Quiz →
