Frequently, the question arises as to what airfoil or airfoils were used in the wing design of a particular aircraft. Jane's All The World's Aircraft has been a good source of this information, but in many cases (particularly military aircraft) it doesn't list this information. To answer this perennial question, the following list has been created. The tip airfoil should also be stall resistant and achieve high CL max at a relatively small RN. These requirements favor a forward loaded airfoil with a round nose. Rutan’s modified Eppler 1230 provided a good baseline for the tip. After analyzing dozens of alternatives, we found the Eppler 1212 was a strong contender.

Senior SuperFans: Redefining the Bladeless Fan > Airfoil AlternativesFor our design alternatives we decided to invest our research into changing the airfoil used in the bladeless fan. The airfoil is the cross section of the fans outer and inner rings. We decided to concentrate on the outlet of where the air exits the ring and how this outlet can affect the dispersion of air. The first design we came up with is a 3mm slit that goes all the way around the fan. We directed the air out of this outlet at a 20 degree angle. This design is similar to the current Dyson model except the opening is a bit bigger and the angle is increased as well. We made these changes with thoughts of how it can increase airflow into the center of the air distribution. We created an airfoil sample of this design which is below.
Another airfoil design we though out of included the same 3mm slit shown above except this time we considered adding small angled blades in the outlet. We inserted these blades with thoughts that they would be able to help control airflow in which ever direction we position the blades. We also created a model of this airfoil design shown below. Our final airfoil design is an improved version of the 2 above. We decided to insert tubes in the outlet at an angle to help create a cyclonic airflow allowing the air to be more controlled. We also think that by adding these tubes into the airfoil we can create a collimation effect which will allow for the exiting air to continue to follow the path created by the tubes in the outlet. We increased the diameter of the outlet to 5mm in this design in order to account for air resistance. Since there is more plastic in the airfoil outlet we see there being increased resistance for the air to exit. Another thing we added to this design was to thicken the wall in which the air will be exiting in order to strengthen the collimation effect. This design is shown below in a model we created through SolidWorks.
