Russia exits from Comac CR929 program

Russia exits from Comac CR929 program

Russia has withdrawn from the Comac CR929 widebody aircraft project with China, according to the report. it is stated, due to long-term effects from the invasion of Ukraine about 18 months ago. Additional difficulties may be present, according to reported delays for United Aircraft Corp.’s (UAC, Moscow) Irkut (Moscow, Russia) MS-21 single-aisle commercial aircraft. Both aircraft programmes make good use of composite materials.

The accuracy of the reports raises intriguing considerations, particularly if one delves into the intricacies surrounding Russia’s sustained participation in the CR929 program despite facing the headwinds of Western sanctions. It is notable that the CR929 programme, a unique joint effort combining the efforts of both China and Russia, has encountered significant obstacles leading to notable delays. Due to these problems, the expected CR929 service launch has been delayed much beyond earlier projections, with a potential post-2030 schedule now being considered.

The lengthy negotiations over the division of labour and the complex sharing of intellectual property rights have been crucial in causing these delays. The continuation of the China-Russia Commercial Aircraft International Corp. (CRAIC), a company founded in 2017 and profiting from China’s moderated stance towards imposing sanctions on Russia, is an important aspect in this scenario.

Yury Slyusar, CEO of United Aircraft Corp. (UAC), recently announced widely that UAC was leaving the CR929 joint venture. Although a decision has been made, it will probably take some time to detangle the agreements between the Russian and Chinese governments in order to cancel the joint venture.

Uncertainties concerning the participation of Western suppliers arise from the complex nature of collaboration, integration, and information exchange in aircraft programmes. Initially, it was anticipated that Western experts would contribute to a number of systems in the CR929 project.

The CR929 is a long-range, wide-body twin-engine aircraft developed by China’s COMAC (Commercial Aircraft Corporation of China) and Russia’s United Aircraft Corporation (UAC). The CR929 aspires to compete in the lucrative market for big passenger planes with major aircraft manufacturers such as Boeing and Airbus. With a passenger capacity ranging from 258 to 320 passenger , the CR929 was created with an outstanding range of up to 12,000 kilometers with consideration.

Similar to the CR929 programme, the MS-21 (or MC-21) programme has experienced delays as a result of the withdrawal of Western suppliers.This Russian-backed project had ambitious aspirations to roll out an astonishing count of 270 units by the time 2030 arrives, with an initial projection of the deployment of MC-21 aircraft by 2024. Due to the significance of this situation, Russian manufacturers have been given more time to properly swap out imported actuators, avionics, and air conditioning components with domestically sourced replacements.

Why do airplane tires cause smoke at touchdown?

Why do airplane tires cause smoke at touchdown?

When an aircraft touches down during landing, the appearance of smoke is a common sight. This occurrence arises from a combination of factors related to the landing procedure and the characteristics of the tires themselves.

As the aircraft descends and prepares for touchdown, the tires are stationary. Upon contact with the ground, they rapidly accelerate from a standstill to an average speed of 240 to 260 km/h. This sudden burst of motion creates friction between the tires and the runway surface, resulting in the emission of smoke.

The smoke stems from the considerable heat generated by the friction between the rubber tires and the asphalt runway. This heat is sufficient to cause the rubber to almost vaporize, resembling the smoke produced when a bike tire skids against the road.

Several variables influence the intensity and occurrence of smoke during landings. The frequency of landings a tire experiences within a specific timeframe, such as within 24 hours, impacts its level of wear and tear. Airlines rigorously inspect tire conditions before each flight, promptly replacing them if any damage or signs of deterioration are detected to uphold safety standards.

The design and resilience of aircraft tires are influenced by the type of aircraft and its operational demands. For example, the tires used on an Airbus A330-200 differ in composition and load capacity compared to those designed for conventional automobiles. Furthermore, environmental factors such as runway temperatures and altitude variations contribute to tire performance.

Aircraft tires are meticulously engineered to endure the demanding conditions of takeoff and landing. They incorporate multiple layers of nylon for reinforcement and a wire core to prevent slippage on the rim. Moreover, these tires are filled with nitrogen, offering superior properties compared to conventional compressed air for aviation purposes.

FedEx B767 Freighter Aircraft Lands in Istanbul Without Nose Gear

A FedEx cargo Boeing 767-300F, bearing registration N110FE, faced a tense situation as it embarked on what should have been a routine journey from Paris’s Charles de Gaulle Airport to Istanbul.

However, mid-flight, the pilots discovered a malfunction in the front landing gear, setting off a chain of events that culminated in a dramatic emergency landing at Istanbul Airport on 8th May.

According to reports from the state-run Anadolu Agency, the crew onboard Flight FX6238 promptly alerted authorities at Istanbul Airport upon realizing the landing gear failure. With nerves of steel, they maneuvered the aircraft under the guidance of the control tower, navigating the challenge of landing without the crucial support of the front landing gear.

As the FedEx plane descended toward the runway, onlookers, and social media users witnessed a nerve-wracking sight: the aircraft relying solely on its back landing gear, gently touching its nose to the tarmac in a controlled landing.
