Engines in nacelles on a Boeing 707.

The nacelle (play /nəˈsɛl/ nə-sell) is a cover housing (separate from the fuselage) that holds engines, fuel, or equipment on an aircraft. In some cases—for instance in the typical "Farman" type "pusher" aircraft, or the World War II-era P-38 Lightning—an aircraft's cockpit may also be housed in a nacelle, which essentially fills the function of a conventional fuselage. The covering is typically aerodynamically shaped.[1]

  • Edward Turner used the term to describe his post-war styling device to tidy the area around the headlamp and instrument panel of his Triumph Speed Twin and Triumph Tiger 100 motorcycles. This styling device was much copied within the British industry thereafter, although Czech motorcycle manufacturer CZ were using it beforehand. Indeed, the Royal Enfield Bullet still retains their version, the 'casquette', on their current models. The last Triumphs to sport nacelles were the 1966 models of the 6T Triumph Thunderbird 650, 5TA Triumph Speed Twin 500, and 3TA Triumph Twenty-One 350.[citation needed]
  • The Triumph Owners' Motor Cycle Club calls its monthly magazine 'Nacelle'.[3] This is named after the Triumph styling device designed by Edward Turner.
  • Name for the generator and gearbox "shell" on a horizontal axis wind turbine (HAWT).
  • Nacelle is used as a name for a minor character in Robert Jordan's series The Wheel of Time.
