Sikorsky is readying its X-2 demonstrator for flight tests late this year. The hybrid design, which looks like a helicopter with two contrarotating coaxial main rotors and one tail propulsor, already had its fly-by-wire system tested in a Schweizer 333. The actual X-2 has undergone engine and drive-train ground tests. Preliminary performance figures call for a 250-knot cruise speed and range of 500 nm.

Eurocopter has launched a 50,000-sq-ft extension of its customization, subassembly and maintenance facility at Mexico City International Airport. In addition, in May the European manufacturer signed three training agreements in the country. The first, with the Mexican Polytechnical Institute, creates a course in aeronautical engineering for helicopters.
Saudi Arabia and the UK have already concluded the huge contract for 72 Eurofighter Typhoon combat jets that has been in negotiation for 18 months, informed sources told Aviation International News yesterday. The deal will be worth about $16 billion for the airframes alone.
Sikorsky announced Tuesday that the kingdom of Bahrain had signed a letter of acceptance for nine Sikorsky UH-60M Black Hawk helicopters, the first export sale for the variant.

Eurocopter CEO Lutz Bertling made it clear at a press conference here in Paris that there will be no synergy between the Korean Helicopter Program (KHP) and the EC 175.

Sikorsky is confident its upgraded medium-twin helicopter, the S-76D, will make its first flight in the fourth quarter of next year, vice president Europe Bruce McKinney said here at the show during a press conference on Monday.
