Tex­tron starts work on the De­nali

Pilot - - PILOT NOTES -

Tex­tron has started build­ing the first static and fa­tigue test air­frames for its forth­com­ing Cessna De­nali sin­gle-en­gine tur­bo­prop. It has also be­gun test­ing the fuel sys­tem on an ‘iron bird’, and test run­ning the air­craft’s Mccauley’s 105 inch di­am­e­ter, five-blade com­pos­ite pro­pel­ler, in­clud­ing runs at max­i­mum rpm and vi­bra­tion and bird strike tri­als. The De­nali will be powered by GE’S new 1,240shp ‘ad­vanced tur­bo­prop’ en­gine with sin­glelever power and pro­pel­ler con­trol. The en­gine is de­signed to pro­vide an ini­tial 4,000hour TBO. In the cock­pit the air­craft will fea­ture a Garmin G3000 ‘in­tu­itive touch-screen’ avion­ics suite that in­cludes high-res­o­lu­tion mul­ti­func­tion dis­plays and split-screen ca­pa­bil­ity, weather radar, ad­vanced Ter­rain Aware­ness Warn­ing Sys­tems (TAWS), and au­to­matic de­pen­dent sur­veil­lance-broad­cast (ADS-B) ca­pa­bil­i­ties which will make it com­pli­ant with a sig­nif­i­cant as­pect of fu­ture NextGen­er­a­tion air traf­fic con­trol re­quire­ments.

The air­craft’s flat floor cabin will have an ex­ec­u­tive seat­ing con­fig­u­ra­tion of six in­di­vid­ual re­clin­ing seats, club­con­fig­u­ra­tion ta­bles and

re­fresh­ment unit, or a com­muter-style lay­out with nine in­di­vid­ual for­ward-fac­ing seats. It will be eas­ily con­vert­ible from pas­sen­ger to cargo con­fig­u­ra­tion. The pres­suri­sa­tion sys­tem will main­tain a 6,130ft cabin al­ti­tude at the air­craft’s 31,000ft ser­vice ceil­ing.

Pre­dicted per­for­mance in­cludes a cruis­ing speed of 285kt, full fuel pay­load of 500kg, and a range of 1,600nm at high-speed cruise with one pi­lot and four pas­sen­gers, en­abling it to fly, for ex­am­ple, non-stop be­tween London-moscow, Los An­ge­lesChicago or New York-miami.

“This is an ex­cit­ing time in the De­nali pro­gramme as this air­craft is now com­ing to life through the pro­duc­tion of the first test ar­ti­cles,” said Brad Thress, Cessna Se­nior Vice-pres­i­dent, En­gi­neer­ing. “The level of at­ten­tion that goes into this phase of de­vel­op­ment re­sults in a highly ma­ture prod­uct in later stages of the de­vel­op­ment pro­gramme, ul­ti­mately al­low­ing us to de­liver cus­tomers a best-in-class air­craft.”
