specific thrust वाक्य
उदाहरण वाक्य
मोबाइल
- Turbofan exhaust gases induce additional air into the ejector via an auxiliary air intake, thereby reducing the specific thrust / mean jet velocity of the final exhaust.
- If, however, the afterburner is to be hardly used, a low specific thrust ( low fan pressure ratio / high bypass ratio ) cycle will be favored.
- At a fixed total applied fuel : air ratio, the total fuel flow for a given fan airflow will be the same, regardless of the dry specific thrust of the engine.
- It's linked to from a wikified table in that article, as an example of a propulsion type which would have very low specific thrust designed to be applied over decades.
- When lit, prodigious amounts of fuel are burnt in the afterburner, raising the temperature of exhaust gases by a significant degree, resulting in a higher exhaust velocity / engine specific thrust.
- An SST VCE would have to increase the engine airflow substantially at take-off, to reduce the jet velocity at a given thrust ( i . e . a lower specific thrust)
- A low ( dry ) specific thrust engine has a low tailpipe temperature, which means that the temperature rise across the afterburner can be high, giving a good thrust boost in afterburning.
- The total fuel flow ( main combustor plus afterburner ) is fixed by the temperature rise from air intake to nozzle and, for a given airflow, changes little with dry specific thrust.
- Ivchenko Lotarev chose a very low specific thrust ( net thrust / airflow ) cycle for the DV-2, so a single stage fan is sufficient to develop the desired fan pressure ratio.
- Military turbofans, however, have a relatively high specific thrust, to maximize the thrust for a given frontal area, jet noise being of less concern in military uses relative to civil uses.
- Thus civil turbofans today have a low exhaust speed ( low " specific thrust " & mdash; net thrust divided by airflow ) to keep jet noise to a minimum and to improve fuel efficiency.
- However, a high specific thrust turbofan will, by definition, have a higher nozzle pressure ratio, resulting in a higher afterburning net thrust and, therefore, a lower afterburning specific fuel consumption ( SFC ).
- The lower the specific thrust of a turbofan, the lower the mean jet outlet velocity, which in turn translates into a high thrust lapse rate ( i . e . decreasing thrust with increasing flight speed ).
- Therefore, a future SST might well benefit from a variable cycle engine, where the specific thrust ( and therefore jet velocity and noise ) is low at take-off, but is forced high during supersonic cruise.
- If the aircraft burns a large percentage of its fuel with the afterburner alight, it pays to select an engine cycle with a high specific thrust ( i . e . high fan pressure ratio / low bypass ratio ).
- However, the ideal Combat VCE would have the high reheat thrust / good reheat SFC associated with a high specific thrust engine, but would have the low SFC of a low specific thrust engine in dry power and throttled back.
- However, the ideal Combat VCE would have the high reheat thrust / good reheat SFC associated with a high specific thrust engine, but would have the low SFC of a low specific thrust engine in dry power and throttled back.
- Curve fitting the data resulted in the specific thrust of 20? �N / W, resulting in the apparent photon momentum multiplication factor of 2, 990?50 and the true OC mirror reflectance used in this demonstration of 0.99967?.00002.
- A very low specific thrust ( i . e . very high bypass ratio ) turbofan is proposed for the aircraft . Engine handling and low jet noise are facilitated by the use of a variable area final nozzle, to rematch the fan.
- Improved materials, and the introduction of twin compressors such as in the thermodynamic efficiency of engines, but they also led to a poor propulsive efficiency, as pure turbojets have a high specific thrust / high velocity exhaust better suited to supersonic flight.
