El C919, realizó su cuarta prueba de alta velocidad en pista el domingo en Shanghai. El ensayo se realizó por primera vez con el tren de aterrizaje delantero suspendido ligeramente a manera de despegue. La nave de un solo pasillo, 168 asientos y doble motor se encuentra a un paso de su primer vuelo, según la Corporación de Aviación Comercial, una empresa estatal con base en Shanghai. Un día antes, la nave recibió su permiso de vuelo otorgado por la Administración de Aviación Civil de China y ya tiene en su poder todos los certificados necesarios de cara a su debut.

El editor en jefe de la revista Aerospace Knowledge, Wang Yanan, indicó que dichas pruebas por lo general se realizan a una velocidad de 230 a 260 kilómetros por hora. De acuerdo con los progresos en el tema, el C919 podría necesitar solo de unos cuantos ensayos más en tierra, recalcó Wang.

«Cada prueba en el terreno se da usualmente aumentando la velocidad hasta llegar a simular condiciones reales de despegue. Si todo sale bien y no hay faltas técnicas graves, la aprobación es rápida”, agregó el editor.

El investigador de un medio especializado en aviación afiliado a la Fuerza Aérea del Ejército Popular de Liberación, Fu Qianshao, señaló que la aerolínea posee una serie de diseños y tecnología innovadoras basadas en la investigación de sus pares internacionales, en especial del Boeing B737 y el Airbus A320.

Por ejemplo, el parabrisas delantero consiste en solo 4 piezas, un diseño que al parecer es más eficiente en cuestión de combustible y más resistente que el que utiliza paneles.

«No hay que subestimar la importancia de los parabrisas”, recalcó Fu. «En comparación con los tradicionales 6 paneles del Boeing 737, es una gran mejora en cuanto a la fortaleza de su estructura, la resistencia del aire y la eficiencia en el uso de combustible”. Además para acomodar motores de mayor potencia, se requirió reforzar el tren de aterrizaje del avíón y aumentar su tamaño.

La nave, de producción china, utiliza una gran cantidad de materiales compuestos y por eso se espera que sea relativamente más ligero y eficiente frente a sus competidores, incluido el renovado A320 y la nueva generación B737, los cuales actualmente dominan el mercado.

Hasta el momento, la corporación ha recibido 570 órdenes de compra de 23 clientes, incluidas empresas nacionales como Air China, Aerolíneas del Sur de China, Aerolíneas del Este de China, Aerolíneas Hainán y la Compañía Aérea de Sichuan. En cuanto a los pedidos internacionales, estos representan el 10% del total procedente de Alemania, Tailandia y de las regiones del Asia-Pacífico y África. AIRGWAYS ® Icon-AW

COMAC C919 set-up for your rollout


The long-awaited commercial passenger plane made in China, the C919, is approaching its premiere by completing its fourth test of high-speed track on Sunday in Shanghai


The C919, made its fourth test of high speed track on Sunday in Shanghai. The test was performed for the first time with the front landing gear suspended slightly to take off. The single-aisle, 168-seat, twin-engine spacecraft is one step away from its first flight, according to Shanghai-based State Commercial Aviation Corporation. A day earlier, the ship received its flight permit issued by the Civil Aviation Administration of China and already has in its possession all necessary certificates in the face of its debut.

The editor-in-chief of Aerospace Knowledge magazine, Wang Yanan, said such tests are usually run at a speed of 230 to 260 kilometers per hour. According to progress on the issue, the C919 may need only a few more tests on the ground, Wang said.

«Every test in the field is usually given increasing speed to simulate actual takeoff conditions. If everything goes well and there are no serious technical faults, approval is quick,» added the editor.

Fu Qianshao, a researcher in a specialized aviation industry affiliated with the People’s Liberation Army Air Force, said the airline has a number of innovative designs and technology based on research from its international peers, especially the Boeing B737 and Airbus A320.

For example, the front windshield consists of only 4 pieces, a design that seems to be more fuel efficient and more resistant than the one that uses panels.

«We should not underestimate the importance of windshields,» Fu said. «Compared to the traditional Boeing 737 panels, it is a great improvement on the strength of its structure, air resistance and efficiency in use made out of fuel». In addition to accommodate larger power engines, the gear was required to reinforce the gear and increase its size.

The Chinese production vessel uses a lot of composite materials and is expected to be relatively lighter and more efficient compared to its competitors, including the refurbished A320 and the new generation B737, which currently dominate the market.

So far, the corporation has received 570 purchase orders from 23 customers, including domestic companies such as Air China, Southern China Airlines, Eastern China Airlines, Hainan Airlines and Sichuan Airline. For international orders, these represent 10% of the total from Germany, Thailand and the Asia-Pacific and Africa regions. A \ W
