Rolls Royce "Spirit of Innovation" all-electric racer FS98 Rolls Royce "Spirit of Innovation" all-electric aircraft --------------------------------------------------------------------- Fastest all-electric racing aircraft to date, built within the Rolls Royce ACCEL Project (Accellerating the Electrification of Flight), using the record-breaking Reno air-racing champion Sharp Nemesis NXT airframe. The power train comprises three 98% efficiency, direct drive, stacked YASA-750R yokeless, segmented armature, axial-flux electric motors powered by a 750-Volt, 216 KWh battery stack. In November 2021, with 345.4 mph (300 kt), the "Spirit of Innovation" broke the electric aircraft world speed record previously held by the Siemens Extra 300LE, and the best climb record with 202 seconds to 3000 metres. Maximum 5-minute Power is rated at 400 KW (535 Hp), giving 300 Kt top speed, and maximum Continuous power is 373 KW (500 Hp), with 282 kt. Practical endurance is 20 to 30 minutes. Electric power is emmulated in FS98 with a Jet .air file with increased Thrust to obtain high electric motor torque for specified 3000-4000 fpm RoC. A 1-USG Fuel Tank acts as Batteries, with a minimal 6.6 lb weight difference between full and empty charges, and Fuel Consumption is reduced to fit specified endurance. Source .AFX, .PCX and .R8 files includes, as well as functional high-visibility Custom panel for FS98 gauges, with custom bitmaps for engine KW power (N1), RPM (N2), and Battery Charge gauges (Acro Tank) are included.
