7. One of the ways we test whether a  jet engine is sturdy enough for flight is by putting it through rigorous testing to simulate real world conditions, from frightening sand storms to ice slabs as thick as cutting boards. Here’s a look at the GEnx engine installed for testing at GE facility in Winnipeg.

8. A look inside our  jetengine testing facility in Peebles, Ohio, where the walls of each of our testing cells are at least 20 feet thick. Built from special high-density concrete, made by vibrating the wet concrete down to squeeze out air and get rid of any weak spots, these testing cells are strong enough to simulate extreme conditions for GE jet engine.

9. The General Electric GE9Xis a high-bypass turbofan aircraft engine under development by GE Aviation for the Boeing 777X. Derived from the GE90

10. The first engine to test (FETT) completed its first test run in April 2016. With 375 cycles and 335 test hours.

11. GE 9x has the largest front fan at 134 inches in diameter with a composite fan case and 16 fourth generation carbon fiber composite fan blades

12. The GE9X went through icing tests in winter 2017. The FETT was finally used for 50 cold weathertest points such as ground fog or natural icing conditions,

13. The initial 777X flight-test engines will be shipped later in 2018 for an initial 777-9 flight in early 2019.

14. In 1995, the GE90 engine debuted aboard a British Airways 777 airplane along with commercial aviation’s first-ever carbon-fiber composite fan blades. Early GE90 engine models boasted outputs between 74,000 and 94,000 lbs. of thrust, and today it remains the world’s largest turbofan engine.

15. With the GE90, GE introduced the composite fan blade—the first-ever in commercial aviation. Measuring more than four feet long and weighing less than 50 pounds, the GE90 fan blade is made from carbon fiber and a toughened epoxy matrix that delivers double the strength and one-third the weight of titanium.

HAL’s Indigenous Tejas MK-1A completes its first maiden flight

The LCA Tejas Aircraft Crash: Understanding the Reasons - Air Marshal GS Bedi's Perspective

The inaugural flight of the first production series fighter of LCA Tejas Mark-1A, an advanced iteration of the LCA Mk-1 recently inducted by the Indian Air Force (IAF), completed its maiden flight in Bengaluru Today.

Over the past several days, the Defence PSU HAL has been conducting various taxi trials in preparation for this milestone.

The maiden flight lasted 18 minutes and marked a triumph for the project. The Mk-1A boasts several enhancements, including digital radar warning receivers, an advanced AESA radar, improved beyond-visual-range (BVR) air-to-air missiles, and external self-protection jammer pods.

The upgraded Tejas Mark 1A aircraft features a larger cockpit canopy, enhancing the pilot’s outside visibility and facilitating better movement of their helmet. Additionally, the air intake has been redesigned to supply faster airflow to the engine, enhancing performance. Modifications to the vertical radar in the tail section have been made to improve control during turns. Overall, these upgrades elevate the aircraft’s standards compared to previous versions, providing increased comfort and functionality.

Under a contract worth Rs 46,898 crore signed in 2021, HAL is mandated to deliver 83 Tejas Mk-1A jets between March 2024 and February 2028. This follows the completion of the order for 40 Tejas Mk1 jets valued at Rs 8,802 crore, of which 32 single-seat fighters and two twin-seat trainers have already been delivered.

The IAF, which currently operates two Tejas squadrons named ‘Flying Daggers’ and ‘Flying Bullets’, has deployed one squadron in the southwestern sector. Recognizing the significance of the Tejas in bolstering its fleet, the Defence Acquisition Council (DAC) has approved the acquisition of an additional 97 Tejas Mk-1A aircraft. However, the final clearance from the cabinet committee on security (CCS) is pending before the order can be placed.

With the IAF grappling with a decline in the number of its fighter squadrons, which currently stands at 31 against the required 42 to effectively counter threats from China and Pakistan, the Tejas assumes a crucial role in filling this gap. Despite initial skepticism, the Tejas has evolved into a flagship platform for India, garnering attention and accolades at numerous defense and aerospace exhibitions worldwide.

However, it is essential to note that the IAF recently experienced its first loss of a Tejas Mk 1 fighter aircraft due to an air crash on March 12.

South Korean KF-21 Completed First Successful Aerial Refueling

South Korean KF-21 Completed First Successful Aerial Refueling

The first aerial refuelling test of South Korea’s indigenous KF-21 Boramae fighter jet was successfully completed, marking a key milestone in the country’s defense capabilities.

Refueling from a Republic of Korea (ROK) Air Force KC-330 aircraft off the southern coast, the Boramae fighter jet took off from Sacheon Airbase, some 183 miles southeast of Seoul. The Defence Acquisition Programme Administration (DAPA) hailed this development, which represents a significant advancement for this state-of-the-art aircraft.

The successful aerial refueling test corresponds with a staged production plan intended to ease worries brought forward by the feasibility assessment carried out a year ago. The research recommended cutting production to just 20 units and made additional test suggestions. A DAPA official continues to state that after discussions with pertinent agencies, plans are in place to conclude verification testing by June of this year and complete a contract for the remaining 20 units by February of the following year.

The kf 21, which has been compared to the Turkish KAAN and the Indian AMCA, has a more stealthy airframe than fourth-generation aircraft, but it is not yet capable of fifth-generation fighter capabilities. However, in the future, modifications such as internal weapons bays might force South Korea to reclassify it as a fifth-generation fighter. Even while South Korea has made significant strides towards constructing the KF-21, other countries, including Turkey and India, are also stepping up their efforts to push plans for creating fifth-generation fighter jets.

As an initial phase, KAI boramae intends to manufacture a two-seat variant of the kai kf 21 boramae equipped with manned/unmanned teaming (MUM-T) capabilities. According to current plans, the Block 2 kf 21 fighter is slated for an upgrade to a low observability (LO) configuration, elevating it to the status of a fifth-generation fighter.

Additionally, KAI has put forward a proposal for the development of a Block 3 kf 21 boramae fighter jet, categorized as a sixth-generation fighter. This iteration would be larger, boasting enhanced stealth features and capabilities. It would incorporate more potent engines and operate within a comprehensive ‘system of systems’ framework, integrating with unmanned effectors for increased effectiveness.

With the KF-21’s production set to start later in the year, DAPA intends to finalise an agreement with KAI by the beginning of 2024. The Republic of Korea Air Force (ROKAF) is expected to receive 120 KF-21 fighters by 2032.

The whole production plan for 40 kf21s has been approved by the Defence Project Promotion Committee, with an estimated cost of 7.92 trillion won (US$5.9 billion) between now and 2028.
