Aviation case studies contain stories and lessons learned. You can find more aviation case studies here:
In the past decade or so, there has been considerable progress in electric storage and motor technology, which are on the verge of moving the aviation industry ahead and opening new opportunities and uses. One example is the eVTOL (Electric Vertical Take-Off and Landing vehicle), where electric engines reduce noise pollution for quieter flights and provide zero emissions to help the environment.
Recent advances in electrical motors, energy storage systems, and power electronics converters (PEC) are leading to aircraft becoming increasingly electrical. However, hybrid technologies are also a viable option for greener air travel. These hybrid engines convert several power sources to the relevant system of the aircraft, adjusting power supply to actual needs during flight.
At different speed regimes in the jet engine, the airflow in the compressor is regulated by variable stator vanes (VSV), which are generally located at the initial stages of the high pressure compressor. This area experiences relatively high pressure and high temperature that progressively increases with modern engine performances.
Flying a helicopter in an unpredictable and changing environment such as the desert or above the sea can lead to the accumulation of several kinds of potential aggressive contaminants, which are not clearly visibly on the bearings of the main shaft of a helicopter rotor. These damaging substances may cause jamming, ultimately leading to crash. The sealing of the swashplate is critical as it protects this aviation equipment from dust, sand, and debris.
How would a helicopter main gearbox (MGB) successfully function without the proper sealing solution? Rotary lip seals are widely used to seal the oil lubricant within the gearbox and protect it from leaking out at where the shaft enters and exits the gearbox. The main gearbox, also known as a transmission, is a critical part in a helicopter’s airworthiness and safety because it is responsible for reducing high input speed.
A high pressure turbine in a jet engine is one of the hottest parts in an airplane since this section is right after the combustion section and can reach extreme temperatures and pressures from the expanding airflow. Maintaining air flow control in this area is key to ensuring the efficiency of the engine because any type of leak is a waste of energy. To maintain a tight control on air flow in the turbine as well as limit vibration, metal shrouds are used, facing the tip of the turbine blades.
