The noise of jet Airplanes
The noise of jet airplanes in flight comes from two components: noise from powertrains and aerodynamic noise. THE NOISE OF POWERTRAINS Noise from the rotating parts of the engine (upstream and downstream blowers, compressor and turbine), It’s about : jet noise (combustion noise and internal noise) The jet noise is caused by the generation of […]

Icing and effects on Aircraft flight
Icing can be defined as a form of contamination consisting of a coating of ice on the surface of an object. In aviation, this will consist of the formation of ice on the surface of an aircraft or inside an engine. Icing is characterized by the presence of super cooled water droplets in the air […]
What’s the promise of Trajectory- Based Operations (TBO) ? what changes to (Air Traffic Management )ATM are expected ?
✈A concept enabling globally consistent performance-based 4D trajectory management by sharing & managing trajectory information. ✈TBO will enhance planning and execution of efficient flights, reducing potential conflicts and resolving upcoming network and system demand/capacity imbalances early. ✈It covers ATM processes starting at the point an individual flight is being planned through flight execution to post […]
Rolls-Royce has conducted the Successful tests of 100% Sustainable Aviation Fuel (SAF) in a business jet engine-the Pearl 700, in Dahlewitz,Germany.
These tests come just weeks after unblended SAF was successfully used for the first time in engine ground tests on a Trent 1000 engine in Derby, UK. RR says,engines for civil & business jet applications can operate with 100% SAF as a full “drop-in” option. At present, SAF is only certified for blends of up […]
