Which low-bypass afterburning turbofan jet engine is used to power the Saab JAS 39 Gripen?
Saab JAS 39 Gripen The Saab JAS 39 Gripen (English: "griffin" ) is a light single-engine multirole fighter aircraft manufactured by the Swedish aerospace company Saab. It was designed to replace the Saab 35 Draken and 37 Viggen in the Swedish Air Force ("Flygvapnet"). The Gripen has a delta wing and canard configuration with relaxed stability design and fly-by-wire flight controls. It is powered by the Volvo RM12, and has a top speed of Mach 2. Later aircraft are modified for NATO interoperability standards and to undertake in-flight refuelling.
Embraer E-Jet E2 family The Embraer E-Jet E2 family is a family of three narrow-body medium-range twin-engine jet airliners developed by Brazilian aerospace company Embraer, replacing the predecessor Embraer E-Jet family. The three variants share the same fuselage cross sections with different lengths and three different new wings, Pratt & Whitney PW1000G geared turbofans in two sizes, fly-by-wire controls with new avionics, and an updated cabin with 40% enlarged baggage bins. Announced improvements per seat are 16 to 24% lower fuel burn and 15–25% lower maintenance cost.
