Emirates completes engine ground testing with 100% SAF

Emirates wants Airbus to design a new super jumbo that is larger than the A380.

Emirates used 100% sustainable aviation fuel to successfully complete the ground engine testing for one of its GE90 engines on a Boeing 777-300ER (SAF). The goal of the ground testing and analysis is to show that the GE90 engine can operate on the specially blended 100% SAF without impairing its performance, necessitating no changes to the aircraft’s systems or additional maintenance for the GE90 engine or Boeing 777-300ER. Over the course of the fuel’s life cycle, SAF can cut carbon emissions by up to 80%.

The ground test results will now pave the way for the airline’s first experimental test flight using 100% SAF in one engine, which is due for take-off this week. The testing activities involved running one engine on 100% SAF and the other on conventional jet fuel to better analyse the fuel system´s behaviour and performance under each fuel type, compare specific outputs of each engine, and ensure seamless operation of the aircraft’s engine and airframe fuel systems during the planned test flight.

During the ground testing at the state-of-the-art Emirates Engineering Centre in Dubai, the aircraft first went through its standard pre-inspection activities. After that, the stationary operating testing began by first running the Honeywell 331-500 auxiliary power unit (APU) on 100% SAF. The APU was then put under full load with SAF to start the engines. The left engine was exercised through its full power range, utilising the same settings that will be used for the experimental flight.

This included idle, ‘take-off’ and ‘climb settings’ at full flight profile durations, running at maximum speed and intensity. Engines were then run at ‘cruise’ settings for 15 minutes. After the simulation ended, the engines were cooled down. Fuels were isolated in separate fuel tanks to maintain segregation of test fuels. Upon completion of the ground test, engine data was downloaded for review, comparison, and analysis.

Emirates has been working with its partners GE Aerospace, Boeing, Honeywell, Neste and Virent  Inc., a subsidiary of Marathon Petroleum Corp throughout 2022 on SAF fuel blend testing. The partners have developed a blend with the same qualities and performance characteristics of conventional jet fuel and have collaborated on the technical analysis and operational requirements surrounding ground testing and experimental flight activities.

The results of this initiative will provide additional data and research around synthetic fuel blend components and biofuels, supporting standardization and future approval of 100% drop-in SAF. Following the successful trial on one engine, Emirates will then continue to develop these initiatives with the engine airframe manufacturers as well as SAF providers with the goal of certifying these blends for commercial use. Currently, SAF is approved for use in blends of up to 50% with conventional jet fuel.

Somalil and ATC Prevents Collision Between Emirates and Ethiopian Airlines

Somalil and ATC Prevents Collision Between Emirates and Ethiopian Airlines

Somalil and’s Air Traffic Control (ATC) played a pivotal role in preventing a potential catastrophe as an Ethiopian Airlines plane narrowly dodged another near-collision incident with an Emirates aircraft over Somalia’s airspace.

The harrowing event unfolded last Sunday, involving flight ethiopian airlines ETH 690 and emirates UAE 722, both cruising at 37,000 feet. According to an incident report released by the Somaliland Civil Aviation and Airports Authority on Tuesday, the two planes were on a collision course after receiving conflicting instructions from Mogadishu Control, placing them on a collision trajectory.

Fortunately, swift action by Somaliland’s ATC, in collaboration with the ethiopianairline
crew, averted disaster. The pilots of the et airline 737 MAX promptly ascended to 39,000 feet, creating a safe distance between the two airliners.

This incident underscores the critical importance of proficient air traffic control in ensuring the safety of airspace, particularly in the Horn of Africa region, which has witnessed similar close calls in recent times. The repeated errors by Mogadishu’s air traffic controllers highlight the pressing need for enhanced oversight and training within the aviation sector.

The Somalil and Civil Aviation and Airports Authority has issued a cautionary statement, warning that such mistakes pose a significant threat to the safety of international flights. They emphasized that the “stubbornness and lack of knowledge” displayed by Mogadishu Tower personnel present a clear danger to air safety.

The government of Somalia has yet to respond to the incident or address concerns raised by Somaliland authorities.

China is secretly testing its next-generation medium combat helicopter Z21

China is secretly testing its next-generation medium combat helicopter Z21

China consistently keeps aviation enthusiasts surprised with its advancements in fighter jets and other aircraft. Leading the pack in Asia, China continuously pushes boundaries in developing domestically-built aircraft.

Recently, images circulating on the internet reveal China’s latest creation, the Z-21 helicopter. Resembling its predecessor, the Z-10, this helicopter boasts enhanced fighter capabilities. The emergence of these images sparks questions regarding the fate of plans to acquire Russian-made Ka-52K attack helicopters, particularly the naval version.

Observing the helicopter in flight, it shares design elements with the Harbin Z-10, notably in the front fuselage and cockpit canopy. The wing stubs for weapon mounts exhibit similar shapes, though with less pronounced angular features. With a tandem seating arrangement, the Z-21 also draws comparisons to the Mil Mi-28, featuring an elongated body with five rotor blades and weapon bays on its sides.

The unveiling of the Z-21 has triggered speculation about its potential role in future military operations. Analysts suggest that beyond its firepower, its introduction could signal significant technological advancements. There’s particular interest in whether China will incorporate a ‘manned-unmanned teaming’ system akin to later Apache models, enabling the Z-21 to control armed drones for reconnaissance and attacks, reducing risks to the helicopter itself.

The emergence of the Z-21 underscores China’s increasing military prowess and its commitment to developing cutting-edge weaponry. Its deployment and capabilities will be closely monitored, especially concerning regional security dynamics.

The helicopter presents a significant challenge to American-built Apache and other medium helicopters, boasting superior capacity for flying at higher altitudes and more powerful speed and combat capabilities, thus enhancing its effectiveness on the battlefield. On the other hand, amidst ongoing Indian border tensions, this aircraft is poised to play a crucial role in surveillance along the sensitive China border and beyond.
