How much data does a jet engine generate?
According to GE, each of its aircraft engines produces around one terabyte of data per flight.
How much data does an aircraft generate?
IBM figures reveal that an average aircraft generates between 500 to 1,000 gigabytes of data.
How efficient is a modern jet engine?
The overall efficiency of commercial aircraft engines has been improving at a rate of about 7 percent per decade since 1970 (see Figures 3.3 and 3.4). Today, the overall efficiency of commercial aircraft propulsion is approaching 40 percent.
How much electricity does a jet engine produce?
For an aircraft like a Boeing 777 with two GE 90-115B engines each engine produces roughly 23 Megawatt of power during cruise flight with a fully loaded aircraft. This is 30.843 horsepower.
How much data does a 787 generate?
Aircraft engines such as in Boeing 787 generates about 1 Terabyte of sensor data every 24 hours.
How much data does a flight recorder record?
Most FDRs record approximately 17–25 hours of data in a continuous loop. It is required by regulations that an FDR verification check (readout) is performed annually in order to verify that all mandatory parameters are recorded.
Can airlines change aircraft?
When you book a flight, you agree on its schedule. However, all airlines reserve themselves the right to change the time (and sometimes even the date) of the flight, as per their terms and conditions. Specifically, airlines do not guarantee flight times and stress that those are not part of the contract of carriage.
Why are airplane engines so inefficient?
Yes, aircraft engines are low tech compared to modern auto engines. They also generally drive their propellers directly rather than through a geared transmission. So they have to run at low RPMs and can’t get high HP per unit volume.
What sensors are used in aircraft?
All sensors installed in aircraft are for flight instruments. These include tachometers, engine temperature gauges, fuel- and oil-quantity gauges, pressure gauges, altimeters, airspeed-measurement meters, vertical speed indicators and others.
How much air does a jet engine take in during takeoff?
A typical commercial jet engine takes in 1.2 tons of air per second during takeoff—in other words, it could empty the air in a squash court in less than a second. The mechanism by which a jet engine sucks in the air is largely a part of the compression stage.
What is the process of a jet engine?
Below is an animation of an isolated jet engine, which illustrates the process of air inflow, compression, combustion, air outflow and shaft rotation just described. The process can be described by the following diagram adopted from the website of Rolls Royce, a popular manufacturer of jet engines.
What is the temperature inside a jet engine?
Inside the typical commercial jet engine, the fuel burns in the combustion chamber at up to 2000 degrees Celsius. The temperature at which metals in this part of the engine start to melt is 1300 degrees Celsius, so advanced cooling techniques must be used.
What type of engines are used in commuter aircraft?
Commonly aircraft are propelled by airbreathing jet engines. Most airbreathing jet engines that are in use are turbofan jet engines, which give good efficiency at speeds just below the speed of sound.
