Twice as fast as Concorde: The supersonic jet that will fly from London to New York in TWO HOURS!
SonicStar plane will have a top speed of Mach 3.6. Plans for 20-seat craft were unveiled at Paris Air Show.

A jet that can fly from London to Sydney in three and a half hours could rob Concorde of its title as the fastest-ever passenger plane.

Plans have been unveiled for the Hypermach SonicStar, a business jet which will be capable of a top speed of 2,664 mph twice as fast as Concorde.

It will fly at 62,000ft, allowing passengers to see the curvature of the earth.

Hypermach chief executive Richard Lugg wants the plane in the skies within ten years (!) and has already secured funding from the Department of Trade and Industry, which has agreed to support the company in Britain.

Return of supersonic travel: The SonicStar aircraft will be twice as fast as Concorde - so quick that travelling from London to New York will take just two hours. It was unveiled at the Paris Air Show.
Long-range cruise speed - Mach 3.1
High-speed cruise speed - Mach 3.4
Engines - Two SonicBlue S-MAGJET Hybrid Supersonic 4000-X Series
Thrust - Flat-rated to 54,700lb
Wing area - 1,800 square feet
Landing distance - 4,800ft
Range - 6,000 nautical miles
Highest Altitude - 62,000ft

CABIN
Length - 64metres
Height at maximum - 2.6metres
Width at maximum - 2.7metres
Visiting the Paris Air Show, Mr Lugg said: “We have access to revolutionary engine technology and a unique very high speed aircraft design to make this kind of earth-shatteringly fast air travel possible, and we have a date. Our plan is to build and fly the world’s first very high speed supersonic hybrid aircraft by June 2021.
Propulsion for the 20-seat aircraft will come from two hybrid engines which will be 30 per cent more fuel efficient than the Rolls-Royce engines used in Concorde.
It has been eight years since Concorde was retired from service and with it the supersonic dreams of millions around the world.
HyperMach claims its SonicStar aircraft will be so quick that travelling from London to New York will take just two hours.
A trip from New York to Sydney, meanwhile, will be cut by a staggering 75 per cent - from 20 hours on a commercial airliner to just five hours.
It will be able to cruise at Mach 3.1, a speed made possible by S-MAGJET hybrid gas turbine engine technology; nobody has ever travelled that fast before.
Its top speed, however, will be Mach 3.6.
With relatively low fuel consumption, the Sonic Star 'overcomes the economic and environmental challenges of supersonic flight to revolutionise the way we travel and drive air transportation forward into the future,' claims HyperMach.
By using electromagnetic currents across the fuselage to suppress the sonic boom, the plane is able to overcome the noise regulations that constrict supersonic travel.
It has a range of 6,000 nautical miles and its 54,700 thrust class S-MAGJET engine - actually two engines - is optimised to fly the aircraft at 62,000ft.
But it is the reduction in jet engine emissions that HyperMach believes will prove the secret of SonicStar's success.

Tomorrow's world: HyperMach plans to build its SonicStar engine by the end of the decade and to have the plane itself constructed by 2025

SonicStar will be able to cruise at Mach 3.1, a speed made possible by S-MAGJET hybridgas turbine engine technology.
A spokesman said: 'The engine is a true hybrid. It generates massive electrical power on board using proprietary integrated turbine electromagnetic generation technology to segment each engine rotating component stage electrically.
'Every stage from bypass fans to compressor to turbine rotates independently of the other.'
This segmentation will enable the engine to change the operating speeds of its rotating components continually throughout the flight to respond to thechanging conditions of the atmosphere and the flight and performance demands of the aircraft. the HyperMach claims that this, along with the S-MAGJET plasma fuel combustion technology, will result in a 40 to 50 per cent increase in the ability of engine to convert fuel to thrust.
The company said such fuel efficiency would ultimately lead to a 30 to 35 per cent reduction in fuel used as supersonic speeds.

Subject: How to Tell a "REALLY-Hard Landing"(gb)

NOW THAT'S A HARD LANDING!!!

DC-9-50 Nearly Loses Engines (‘Yes’, both…) during landing:

Douglas DC-9-51 (operated by Aeropostal) landed at Puerto Ordaz,
Venezuela, with enough force to crack both engine pylons at the
airframe, leaving both engines “dangling” from the rear-fuselage sides.

None of the five-crew and 125-passengers were seriously injured, & all were
evacuated onto the runway after the aircraft was stopped.

The jet, registered as “YV136T”, is more than 35-years-old. The flight (VH #342),
according to the Aviation Safety Network, had operated from Caracas, & landed at Puerto Ordaz in a manner that has been described as "very hard."

A passenger told El Nacional that the impact with the runway had
been hard, & that afterward there was a slight ‘burning-smell’ in
the aircraft. Passengers were reassured by the crew, & aided with
evacuation. The aircraft was later towed from the runway.

It was a regularly-scheduled domestic flight. No local weather reports were
immediately available.

According to El Universal of Caracas , the investigation is being initiated by the JIAAC, the civil aviation accident-investigation agency of Argentina.

The incident aircraft was fitted with Pratt & Whitney JT-8D-17A (HK3) engines.

It was first operated commercially by Finnair from October of 1976 through March
of 1984; and has since served with Alisarda, Linea Aeropostal Venezolana, and Aeropostal.
