Berger 1 Daniel Berger Liberty University AVIA305: Airplane Aerodynamics (D03) Professor Peter Spahr November 27, 2023 Research Paper: Outline Assignment Introduction Given the nickname “Bruce Wayne’s private plane” the Cobalt Co50 Valkyrie was made to be the most stylish, fastest, and safest luxury private aircraft. This staggering aircraft was designed to look like a fighter jet but provides a comfortable luxurious cockpit. Reaching the target audience of civilian pilots who wish to fly fighter jets. The Valkyrie was designed by David Loury, with the primary focus to performance and safety, making it the fastest single-engine piston aircraft in the five-seat category. About the Cobalt Co50 Valkyrie A. Design and Features 1. Features a canard with a forewing design, inspired from military fighter aircrafts to give a smooth, aerodynamic feeling.
2. Retractable landing gear, anti-ice equipment, rescue parachutes. B. Engine/Propeller 1. The aircraft is powered by a single twin turbo piston creating 350 base horsepower, producing a max cruising speed of 260 knots. 3. The engine is driven by three bladed aluminum pusher propeller with automatic variable pitch control, reaching altitudes upward of 25,000 feet. C. Cabin details 1. A large, single piece canopy with a forward tilting glasshouse cabin providing a 320- degree view for all five occupants. 4. A quite cabin, leather seats, plenty of storage, and oxygen for all five occupants. 5. Avionic systems include Garmin G3X touchscreen with synthetic vision integrated with a three-axis autopilot option. Modern electronic displays on the dashboard and room for personal devices as flight controls are managed by mechanical side sticks. Aerodynamic Forces A. Airfoil design 1. Has a canard configuration, with a forewing that helps prevent stalls. 6. Twin vertical stabilizers and automatic airbrakes. 7. Vertical stabilizers on each wing tip along with a V shaped tail on the fuselage, used to help the general stability of the aircraft.
8. Split flaps produce greater increase in lift, creating more drag due to the turbulent air pattern produced behind the airfoil. 9. Frise-type ailerons to generate higher angle of attack. Maneuverability/Performance A. Ailerons 1. Frise-type ailerons forms a slot for smooth airflow over the lowered aileron for an effectively higher angle of attack. 10. The aileron being raised pivots on an offset hinge to help create drag from the airflow to the leading edge. B. Airbrakes 1. Applied to safely slow down the aircraft increasing drag when engaged. 11. Used to help control speed on a rapid decent and slow the aircraft to a safe airspeed not exceeding structural speed. C. Performance 1. 250 knot cruising speed offers a range of 1,150 nautical miles. 12. Maximum payload of 1,200 pounds. 13. Take-off obstacle 1,500 feet, landing ground roll of 1,100 feet, and climb rate of 1,500 feet per minute. Can hold 109 gallons, burning 15 per hour. Conclusion

A. The Cobalt Co50 Valkyrie was originally designed for private pilots’ enjoyment. In attempt to bring a crossover from military fighter jets to civilian aviation. B. Was created with the focus on performance, luxury, and safety. The Valkyrie is still one of the fastest single engine propeller aircraft to date. C. It is a shame that the Cobalt Co50 Valkyrie was not more successful in reaching its target audience and becoming a popular aircraft in the aviation industry, as it had a very bright future.
