NACA 0012 with modifications?
The Gulfstream G150 utilizes the NACA 0012 airfoil for its wing design. This symmetrical airfoil is known for its balanced lift and drag characteristics, which contribute to the aircraft's performance and stability across various flight conditions. The 0012 profile allows for efficient cruising and improved handling, making it suitable for the G150's operational requirements.
The Gulfstream G550 utilizes a modified NACA 0012 airfoil for its wings. This airfoil, characterized by its symmetrical shape, provides good lift and a favorable drag-to-lift ratio, which enhances the aircraft's performance during various flight conditions. The design is optimized for high-speed cruise and efficiency, contributing to the G550's long-range capabilities and overall aerodynamic efficiency.

Which Gulfstream? There are different models but here is an example: Gulfstream G450 High Speed Cruise: 476 knots the High Speed Cruise for other Gulfstream jets can be found on the link below.
The price of a Gulfstream G450 typically ranges from $15 million to $25 million, depending on factors like age, condition, and customizations. As a pre-owned aircraft, prices can vary significantly based on market demand and specific features. Maintenance history and upgrades can also influence the final price.
The maximum lift coefficient of a NACA-4412 airfoil is typically around 1.4 to 1.5 in ideal conditions. This value can vary depending on factors such as angle of attack, Reynolds number, and airfoil surface condition.
The NACA 1-series airfoil series is a set of airfoils characterized by low camber and thickness, typically used for low-speed applications such as general aviation aircraft and wind turbines. These airfoils offer good lift-to-drag ratios at low Reynolds numbers, making them efficient for applications where low-speed performance is important.
The Airbus A320 uses a modified version of the NACA 0012 airfoil for its wings, particularly in the wing's high-lift devices like flaps. The NACA 0012 is a symmetrical airfoil, providing a balance of lift and drag characteristics, making it suitable for a commercial aircraft. Its design allows for efficient performance during various phases of flight, including takeoff and landing. Modifications enhance its performance characteristics to meet the specific requirements of the A320's operational profile.
In 1939, Eastman Jacobs at the NACA in Langley, designed and tested the first laminar flow airfoil sections. These shapes had extremely low drag and the section shown here achieved a lift to drag ratio of about 300.
Modern airplanes have swept wings and so the NACA airfoil system is hard to apply since it it is constantly changing throughout the wing. Even if it was still in use, or another system is in use, the fact is that most companies keep these values extremely confidential since the wing is the most important part of a plane and they dont want other companies copying their airplanes.
min lift coeff of 1412 =.60 thefore Cl will be 1.10 at angle of attatck 4 and mach .8
depends on many things... market,year,total time, but i know someone who paid 50 million, when you could get a G450 for more than 10 million less.... the demand for the g5 is crazy though so people will pay ;)
