Cirrus poised to fly first Vision SF50

Cirrus Aircraft’s ambition to be the first to market with a single-engined personal jet looks set to become a reality, as it prepares its Vision SF50 prototype for first flight next month. The certification aircraft, C-Zero, will be used for flight performance verification. The two remaining test aircraft – C-One and C-Two – are scheduled to enter service in the second and fourth quarter, and will be used for systems verification and parachute testing, respectively.

An earlier configuration "technology demonstrator" – dubbed V1 – has accumulated around 800 flying hours and 1,000 engine runs since it was built in 2008. However, the new prototypes are more reflective of the production jet, says Cirrus executive vice-president of sales marketing Todd Simmons.

"The purpose of V1 has been to verify and validate the Vision jet design," Simmons says. "C-Zero is the summation of everything we have learned from V-1. For example, we have slightly changed the size and shape of the ruddervators, stabilisers, tail arm and the wing root junction.

"We have also made slight changes to [the] aerodynamic shape of the fuselage, [the] engine mount and its position on the aircraft, along with the interior. To the casual observer C-Zero will not look any different to V1."
The Vision has been a key focus for Cirrus since its launch more than seven years ago. Even during the economic crisis and the funding shortage that ensued, the Duluth, Minnesota-based airframer continued to work on the programme – albeit on a piecemeal basis.

The acquisition of Cirrus in 2011 by China Aviation Industry General Aircraft gave the programme new momentum. "CAIGA has committed $100 million to bring the Vision to market," Simmons says. "We are on track to certificate and deliver the first aircraft in 2015."

The $1.96 million Vision is equipped with a Garmin G3000 cockpit and an emergency parachute system. Powered by a Williams International FJ33 turbofan, the aircraft has a range of 1,200nm (2,220km), a stall speed of 61kt and a cruise speed of 300kt (556km/h).

Cirrus has secured 550 orders for the Vision to date – each with a $100,000 deposit. "Our customers range from [Cirrus] SR22 piston single operators to owners of high performance piston twins and single-engined turboprops, all wanting to move to a jet platform," says Simmons.

 "Our position holders come from across the globe, so once we have secured US approval we will get to work [certificating] the aircraft in the countries where our customers are based." Cirrus plans to offer a dedicated training programme to enable customers to secure their Vision type rating.


Comment: The SF50 is among the league of Very Light Jets (VLJ's) and it is scheduled to enter into service soon. A  few other entrants like the Honda Jet is anticipatory scheduled for entry into service in third/fourth quarter of 2014, however, there are few in operation such as the 

Eclipse 500 from Eclipse Aviation 
Embraer 100 and 500 from Brazil's Embraer 
Citation Mustang from Cessna

AERO 2012: Cirrus vision for SF50 to become reality 'in 2015'

Cirrus Aircraft has been given the go-ahead by its new owner to accelerate development of the Vision SF50 personal jet. China Aviation Industry General Aircraft (CAIGA), which acquired the Duluth, Minnesota-based general aviation manufacturer last year, has pledged $100 million to bring the seven-seat, single-engined aircraft to market.

"This should be within three years," says Ian Bentley, Cirrus vice-president and managing director of international sales. "We have been committed to this program since its launch over six years ago. When the economic downturn struck we were forced to slow development considerably, but even throughout this turbulent period we have been working at a low level to iron out any potential technical problems that we might encounter during the SF50 certification process."

Cirrus has already invested more than $45 million in the SF50, which made its first flight in July 2008. The non-conforming prototype has completed more than 600 flying hours to date, and Cirrus has carried out "detail design, systems verification and full flight envelope testing since then", adds Bentley.

Cirrus is now building the tooling for the first of three production-conforming aircraft, which should take to the skies for the first time in 15 months. "A handful of minor modifications will be incorporated in the production aircraft. For example, the cabin will be sightly wider and the sweep on the tail will be slightly reduced, says Bentley.

Cirrus has clocked up 500 orders for the Vision. "In 2008 we had around 400 orders. When the program was slowed we lost around 100 of these but have since added another 200, of which around 60% are from US-based customers," says Bentley.

The SF50 has a cruise speed of 300kt (555km/h) and a range of 1,000nm (1,850km). The aircraft is priced at $1.72 million until 30 June, when it will rise to $1.96 million. Cirrus plans to manufacture 75 Visions in the first year of production, "rising to a steady production rate of 125 aircraft a year", says Bentley.
