China tests new stealth fighter; eyes export sales

December 26, 2016

Beijing, Dec 26: China has tested an improvised version of its stealth fighter and plans to sell it at half the price of the US variant to break Western monopoly over the high-tech aircraft, which will have strategic implications for India as Pakistan has already shown interest in acquiring it.plane

An improved version of China's fifth-generation FC-31 Gyrfalcon stealth fighter jet has conducted its maiden flight last week in Shenyang, capital of Liaoning province, state-run China Daily reported today.

Previously known as the J-31, the twin engine, radar evading aircraft is still under development by Shenyang Aircraft Corp, part of the Aviation Industry Corp of China, (AVIC), it said.

The Chinese stealth aircraft have strategic significance for India as besides China, Pakistan - which is producing JF-17 Thunder fighter along with Beijing - has already evinced interest in acquiring China's stealth fighter.

India is yet to have stealth aircraft in its arsenal. AVIC displayed a large-scale model of the FC-31 at the 14th Dubai Airshow in the UAE in November, 2015.

Specifications supplied by AVIC show the jet has a maximum takeoff weight of 28 metric tonnes, a flight radius of 1,250 kms and a top speed of Mach 1.8, or 1.8 times the speed of sound.

It can carry eight tonnes of weapons. The plane can hold six missiles in its internal weapons bay and another six under its wings, AVIC said.

The first test flight of the FC-31's second prototype took place on Friday at Shenyang Aircraft Corp, four years after the first prototype took to the skies, the Daily quoted officials as saying.

The report also said fifth-generation fighters are the most advanced available. Fu Qianshao, an aircraft expert with the PLA Air Force, said the new FC-31 has state-of-the-art instruments such as its electro-optical targeting system and helmet-mounted display and sight system.

The new FC-31 seems to have better stealth capabilities, improved electronic equipment and a larger payload capacity, said Wu Peixin, an aviation industry observer in Beijing said.

"Compared with the first FC-31, there are a lot of improvements on the second prototype. Changes were made to the airframe, wings and vertical tails, which make it leaner, lighter and more manoeuvrable," he said.

AVIC wants to use the FC-31 to capture market share at home and abroad but the company is making a big push to attract foreign buyers with its medium-sized stealth combat planes, he said.

Li Yuhai, deputy general manager of AVIC, previously said AVIC plans to use the FC-31 to "put an end to some nations' monopolies on the fifth-generation fighter jet" and this plane "is able to compete with any other aircraft of its kind".

"I believe the aircraft will have bright prospects in the market. Based on my experience and knowledge, I presume its price will be around USD 70 million, about half that of the US' Lockheed Martin F-35 Lightning II," Fu said.

"Moreover, the fourth-generation Euro fighter Typhoon and Dassault Rafale fighter jets are priced at about USD 100 million. All of these mean you can spend a lot less money to get an advanced, fifth-generation stealth combat plane," Fu told the Daily.

The only fifth-generation fighter jet currently available in the market is the US' F-35 Lightning II, but the US sells it only to allies.

Following the Friday test flight, aviation enthusiasts posted pictures on Chinese websites, showing what they said was the second prototype in flight.

The FC-31 was unveiled in October, 2012, when the first prototype made its maiden flight, becoming the country's second fifth-generation fighter jet following the J-20, which conducted its first flight in January, 2011.

Deliveries of the J-20 to the People's Liberation Army Air Force have started.

Washington, Feb 18: The upcoming visit of President Donald Trump to India later this month has the potential to usher in a new era of bilateral ties between the two countries, a top American business advocacy group has said.

President Trump will pay a state visit to India on February 24 and 25 at the invitation of Prime Minister Narendra Modi. He would be accompanied by First Lady Melania Trump.

This would be the president's first bilateral visit in the third decade of the 21st century and also the first after his acquittal by the Senate in the impeachment trial.

"I believe President Trump's upcoming visit to India has the potential to usher in a new era of our bilateral ties," Mukesh Aghi, President of the US India Strategic and Partnership Forum (USISPF) said in a statement on Monday.

On the sidelines of the visit, the USISPF, in collaboration with the Federation of Indian Chambers of Commerce and Industry (FICCI) and the ORF, has announced to organise a program entitled "US-India Forum: Partners for Growth".

The full-day discussion will focus on the key pillars defining India and the US' strategic, economic, and cultural partnership over the next decade.

"We have an opportunity before us to make real progress on multiple aspects of the relationship— whether it is upholding peace and security in the Indo-Pacific region; building upon an already strong energy partnership; developing co-production and co-development opportunities in the defense space; or strengthening bilateral trade," Aghi said.

"We look forward to an extremely successful visit and some concrete outcomes from the visit," he said.

The day-long programme on February 25 in New Delhi, will bring together over 500 senior business executives, members of the US-India think tank community and leading figures of the Indian diaspora to set the agenda for this strategic partnership.

Discussions during the day will touch upon areas, including the Indo-Pacific Strategy and Maritime Security; the US-India Defence Partnership, the US-India Energy Partnership, Elevating US-India Trade and Investment and Role of the Indian Diaspora in US-India Relations.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

New Delhi, Apr 14: The World Health Organization on Tuesday lauded "India's tough and timely actions" against the coronavirus spread as Prime Minister Narendra Modi announced the extension of current lockdown till May 3.

"It may be early to talk about results in numbers, but a six-week nationwide lockdown to facilitate effective physical distancing, coupled with the expansion of core public health measures such as detection, isolation and tracing contact of coronavirus positive people, would go a long way in arresting the virus spread," said WHO's South-East Asia Regional Director, Dr Poonam Khetrapal Singh.

"Despite huge and multiple challenges, India has been demonstrating unwavering commitment in its fight against the pandemic," she said.

"In these testing times, the action lies as much with the communities as with the authorities and the health workforce," she added.

"It is indeed time for each and every one to contribute their best and together to beat the virus," Dr Singh said.

Modi on Tuesday said the implementation of the lockdown will be strictly ensured in coming days to ensure that the virus does not spread to new areas

The prime minister said a detailed guideline on the implementation of the new lockdown will be announced on Wednesday.

According the Union Health Ministry figures, a total of 339 people have died of COVIOD-19 till date in the country, while the number of infected cases has soared to 10,363 on Tuesday.

A PTI tally of figures reported by various states as on Monday evening, however, showed at least 346 deaths.

There has been a lag in the Union Health Ministry figures, compared to the number of deaths announced by different states, which officials attribute to procedural delays in assigning the cases to individual states.
