Available in PDF, EPUB and Kindle. Book excerpt: Tests were made on an NACA 23012 airfoil fitted with a 20-percent-chord, true-contour aileron with 35-percent-chord, extreme blunt-nose balance. The tests were made in the two-dimensional test section of the NACA stability tunnel at a range of airspeeds from 160 to 360 miles per hour, which corresponded to a range of Mach numbers from 0.195 to 0.475. The primary purpose of the investigation was to determine the variation of the aerodynamic characteristics of this type of aileron with airspeed; the effect of variations of gap width and balance-nose radii was also investigated.

Available in PDF, EPUB and Kindle. Book excerpt: Hinge moment, lift, and pressure-distribution measurements were made on a Frise aileron on an NACA 23012 airfoil in the two-dimensional test section of the LMAL stability tunnel. Speeds up to 360 miles per hour corresponding to a Mach number of about 0.470 were used. The nose radius of the aileron was varied from 0.0012 to 0.0150 of the airfoil chord. Tests also were made with an increased vent gap and with the lower surface of the airfoil at the entrance of the slot rounded to a radius of 0.02 of the airfoil chord. The primary purpose of all tests was to determine the effects of speed on this type of aileron.

Available in PDF, EPUB and Kindle. Book excerpt: Hinge-moment, lift, and pressure-distribution measurements were made in the two-dimensional test section of the NACA stability tunnel on a blunt-nose balance-type aileron on an NACA 66,2-216 airfoil at speeds up to 360 miles per hour corresponding to a Mach number of 0.475. The tests were made primarily to determine the effect of speed on the action of this type of aileron. The balance-nose radii of the aileron were varied from 0 to 0.02 of the airfoil chord and the gap width was varied from 0.0005 to 0.0107 of the airfoil chord. Tests were also made with the gap sealed.

Available in PDF, EPUB and Kindle. Book excerpt: Pressure-distribution tests of an NACA 66,2-216, a = 1.0, airfoil, equipped with a blunt-nose-balance aileron and a sealed internal-balance aileron, and of an NACA 23012 airfoil, equipped with a Frise aileron and a blunt-nose- aileron, were made in the two-dimensional test-balance section of the LMAL stability tunnel. The tests were made at various airspeeds corresponding to Mach numbers of approximately 0.20 to 0.47. The pressures were measured on the upper and lower surface at the mid-spans of the main airfoil and the aileron for several different aileron deflections at several angles of attack.

Download or read book Wind-tunnel Tests of a Blunt-nose Aileron with Beveled Trailing Edge on an NACA 66(215)-216 Airfoil with Several Modifications of Aileron Nose and Adjacent Airfoil Contour written by J. D. Bird and published by . This book was released on 1945 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: Ailerons having a beveled trailing edge and a blunt-nose overhand of 35 percent aileron chord on an NACA 66(215)-216 airfoil have been tested in the two-dimensional-flow test section of the Langley stability tunnel. Five configurations of the model were tested with various modifications of the aileron nose and adjacent airfoil contour to determine the effect of these modifications on the lift and aileron hinge-moment characteristics. The results indicated that making the nose of the aileron more elliptical decreased the balance of hinge moments at small aileron angels and increased the balance of hinge moments at large aileron angles. The lift coefficients, especially at large aileron angles, were increased by this modification. Flaring the airfoil contour near the aileron nose had an effect on the hinge moments for small aileron angles similar to the effect of making the aileron nose less blunt, whereas rounding the airfoil contour had an effect similar to making the aileron nose more blunt. Flaring the airfoil contour caused a decrease in the lift resulting from aileron deflection. The effects of airfoil-contour changes were small at large aileron angles. Comparison with other data indicated that, for small aileron angels, the increments of hinge-moment coefficient resulting from a beveled trailing edge and a blunt-nose overhang were additive.

This book was released on 1942 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the LMAL 7- by 10-foot tunnel of various modifications to the trailing edge of a 0.155-chord plain aileron on a semispan model of the tapered wing of a fighter airplane. The modifications considered in the present report were: (1) plain and unrigged ailerons with fixed positive tabs to provide upfloating tendencies and allow reduction of stick force through the use of conventional differential aileron linkages; and (2) plain and downrigged ailerons with fixed negative tabs to provide downfloating tendencies and allow reductions of stick force through the use of reversed differential aileron linkages. The effect of a gap at the aileron nose was investigated for each of the basic modifications.
