British Aerospace Jetstream 41 - Design and Development

Design and Development

The Jetstream 41's stretch added 16 feet (4.88 m) to the fuselage, consisting of an 8 foot 3 in (2.51 m) plug forward of the wing and a 7 feet 9 inches (2.36 m) plug to the rear; the fuselage design was all new and did not contain any parts of the old fuselage. The new design demanded a wing with increased span, which also included reworked ailerons and flaps. The wing is also mounted below the fuselage, so that it did not carry through the cabin aisle, also allowing increased baggage capacity in the larger wing root fairings.

The Allied Signal TPE331−14 engines deliver 1,500 shp (1,120 kW), (later 1,650 shp (1,232 kW)), and are mounted in nacelles with increased ground clearance. The flightdeck is improved with a modern EFIS setup, and a new windscreen arrangement. The J41 was the first turbo-prop certified to both JAR25 and FAR25 standards.

Famous quotes containing the words design and/or development:

    Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.
    Ralph Waldo Emerson (1803–1882)

    Dissonance between family and school, therefore, is not only inevitable in a changing society; it also helps to make children more malleable and responsive to a changing world. By the same token, one could say that absolute homogeneity between family and school would reflect a static, authoritarian society and discourage creative, adaptive development in children.
    Sara Lawrence Lightfoot (20th century)
