Spectrum S-40 Freedom

From Wikipedia, the free encyclopedia

The Spectrum S-40 Freedom is a proposed business jet that is expected to be classified as a very light jet. During the 2006 NBAA Conference in Orlando, FL, Spectrum Aeronautical announced development of their second VLJ, the S-40 Freedom. Although the S-40 Freedom features a cabin comparable to the Lear 60, Hawker 800 and the Citation XLS, at a Max. Take-Off Weight of less than 10,000 lbs. the aircraft should still be considered a VLJ, just like the S-33 Independence. The Spectrum S-40 Freedom is a new, mid-size Very Light Jet designed and built by Spectrum Aeronautical, LLC using a revolutionary graphite-epoxy construction process that gives the aircraft essentially the same size cabin as other popular 8-9 seat light business jets, at less than two-thirds the weight. The aircraft is designed to cruise at 45,000 ft. at speeds up to 435 knots (Mach 0.76) and fly as far as 2030 nm (3750 km) while using about half the fuel of comparably sized traditional business aircraft.

FAA and JAA Type Certifications of the S-40 Freedom are estimated for 2010. The mid-size Spectrum Freedom S-40 is the newest aircraft in the Spectrum Aeronautical line. Built utilizing the same unique all carbon-fiber epoxy construction technologies, the S-40 expands on the idea of the S-33 Independence with a cabin size in the same class as Lear 60, Citation XLS and Gulfstream G150 – while still delivering superior economics, utility and performance. Spectrum Aeronautical is one of two launch customers for the HF120 engine from GE Honda. The retail sales price of the aircraft is $6.2 (in 2006 dollars).

[edit] Technology

The S-40 has a full six foot, stand-up cabin, IFR ranges better than 2,200 nautical miles and speeds over 430 nautical miles per hour Inside, the cabins of both the S-30 and the S-40 are the quietest and most comfortable in their classes. This is because the engines are positioned further back & cabin pressure differential is 10 PSI.
