Rolls-royce launches lat­est M250 en­gine vari­ant


Rolls-Royce, the global power sys­tems com­pany, has launched the lat­est vari­ant of its M250 en­gine – the M250C47E. Rolls-Royce has se­cured a com­mer­cial launch com­mit­ment for one new and two cur­rent air­craft ap­pli­ca­tions, with a cus­tomer an­nounce­ment ex­pected at Heli Expo.

The US Navy has com­mit­ted as the first mil­i­tary cus­tomer to in­cor­po­rate the M250C47E into the Northrop Grum­man MQ-8C Fire Scout. Rolls-Royce has de­liv­ered a devel­op­ment en­gine to Northrop Grum­man for a demon­stra­tor air­craft for the rapid de­ploy­ment ca­pa­bil­ity pro­gramme.

The new M250-C47E im­proves ef­fi­ciency and per­for­mance, us­ing proven tech­nol­ogy al­ready demon­strated in the field. Th­ese in­clude a five per cent im­prove­ment in ‘hot and high’ power and a nearly eight per cent in­crease in rated take­off power to 700 shaft horse­power. Spe­cific fuel con­sump­tion (SFC) is re­duced by a typ­i­cal two per cent and en­gine re­li­a­bil­ity is in­creased.

Greg Fedele, Rolls-Royce, Se­nior Vice Pres­i­dent–He­li­copters, said, “The new­est evo­lu­tion of the M250 en­gine will de­liver im­proved power and re­li­a­bil­ity with re­duced fuel con­sump­tion.”

“Both com­mer­cial and mil­i­tary cus­tomers will ben­e­fit from th­ese im­prove­ments as we con­tinue to evolve the proven legacy of the M250 en­gine.” Rolls-Royce has de­liv­ered more than 31,000 M250 en­gines, with the fleet to­talling over 223 mil­lion flight hours.
