High bypass turbofan jet engines & contrails

WebWhat is the formula for Power? Power = Force x Distance / Time or P = F x D / t. meaning P = Power in ft. pounds per minute, D = distance in feet and t = time in minutes. What is the formula for Horsepower? Horsepower = Power (in ft. lbs./min.) divided by 33,000 or HP = Power/33,000. What is the formula for Velocity? Engines with more jet thrust relative to fan thrust are known as low-bypass turbofans, those that have considerably more fan thrust than jet thrust are known as high-bypass. Most commercial aviation jet engines in use today are high-bypass, and most modern fighter engines are low-bypass. Ver mais The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves Ver mais Low-bypass turbofan A high-specific-thrust/low-bypass-ratio turbofan normally has a multi-stage fan behind inlet guide vanes, developing a relatively high pressure ratio and, thus, yielding a high (mixed or cold) exhaust velocity. The core … Ver mais Cycle improvements Consider a mixed turbofan with a fixed bypass ratio and airflow. Increasing the overall pressure … Ver mais Aerodynamic modelling Aerodynamics is a mix of subsonic, transonic and supersonic airflow on a single fan/gas compressor blade in a modern turbofan. The airflow … Ver mais The turbofan was invented to improve the fuel consumption of the turbojet. It would do this by increasing the mass and lowering the speed … Ver mais Early turbojet engines were not very fuel-efficient because their overall pressure ratio and turbine inlet temperature were severely limited by the technology and materials available at the time. The first turbofan engine, which was only run on a test bed, … Ver mais Turbofan engines come in a variety of engine configurations. For a given engine cycle (i.e., same airflow, bypass ratio, fan pressure ratio, overall pressure ratio and HP turbine rotor inlet temperature), the choice of turbofan configuration has little impact upon the … Ver mais
