  • Effects of Gurney Flap on Supercritical and Natural Laminar Flow Transonic Aerofoil Performance
    Effects of Gurney Flap on Supercritical and Natural Laminar Flow Transonic Aerofoil Performance Ho Chun Raybin Yu March 2015 MPhil Thesis Department of Mechanical Engineering The University of Sheffield Project Supervisor: Prof N. Qin Thesis submitted to the University of Sheffield in partial fulfilment of the requirements for the degree of Master of Philosophy Abstract The aerodynamic effect of a novel combination of a Gurney flap and shockbump on RAE2822 supercritical aerofoil and RAE5243 Natural Laminar Flow (NLF) aerofoil is investigated by solving the two-dimensional steady Reynolds-averaged Navier-Stokes (RANS) equation. The shockbump geometry is predetermined and pre-optimised on a specific designed condition. This study investigated Gurney flap height range from 0.1% to 0.7% aerofoil chord length. The drag benefits of camber modification against a retrofit Gurney flap was also investigated. The results indicate that a Gurney flap has the ability to move shock downstream on both types of aerofoil. A significant lift-to-drag improvement is shown on the RAE2822, however, no improvement is illustrated on the RAE5243 NLF. The results suggest that a Gurney flap may lead to drag reduction in high lift regions, thus, increasing the lift-to-drag ratio before stall. Page 2 Dedication I dedicate this thesis to my beloved grandmother Sandy Yip who passed away during the course of my research, thank you so much for the support, I love you grandma. This difficult journey would not have completed without the deep understanding, support, motivation, encouragement and unconditional love from my beloved parents Maggie and James and my brother Billy.

  • SBM20-322 2015 June 23 Temporary
    MOONEY INTERNATIONAL CORPORATION SERVICE BULLETIN 165 Al Mooney Road North Kerrville, Texas 78028 SERVICE BULLETIN M20-322 Date: June 23, 2015 THIS BULLETIN IS FAA APPROVED FOR ENGINEERING DESIGN SUBJECT: Temporary Replacement of Icing System Stall Strip MODELS/ SN Mooney Aircraft with Known Icing System Installed AFFECTED: TIME OF AS SOON AS PRACTICABLE COMPLIANCE: INTRODUCTION: For instances involving missing icing system stall strips, airplanes are grounded. To remedy this situation, a temporary non-icing system stall strip can be installed in place of the icing stall strip to allow the aircraft to operate as a “Not Certified for Flight in Known Icing Conditions” aircraft until the icing strip can be installed. This Service Bulletin is to provide instructions for installing the temporary stall strip. The attached compliance card needs to be filled out and returned to Mooney International Corporation upon completion of this Service Bulletin M20-322. WARNING: Flight into known icing conditions and the use of the aircraft’s icing system is prohibited until the permanent icing system stall strip can be installed. This Service Bulletin only allows for a temporary non-icing stall strip to be installed for temporary flight until the permanent icing stall strip can be obtained. INSTRUCTIONS: Read entire procedures before beginning work. INSTALLING TEMPORARY STALL STRIP: 1.1. Disable and secure circuit breaker to prevent accidental operation of icing system. 1.2. Remove all old sealant and thoroughly clean the porous surface of the wing where the temporary stall strip is to be installed. Acceptable cleaning solvents are listed below. NOTE: The primary factor affecting the adhesion of the stall strip is absolute cleanliness of the porous panel.

  • Unusual Attitudes and the Aerodynamics of Maneuvering Flight Author’S Note to Flightlab Students
    Unusual Attitudes and the Aerodynamics of Maneuvering Flight Author’s Note to Flightlab Students The collection of documents assembled here, under the general title “Unusual Attitudes and the Aerodynamics of Maneuvering Flight,” covers a lot of ground. That’s because unusual-attitude training is the perfect occasion for aerodynamics training, and in turn depends on aerodynamics training for success. I don’t expect a pilot new to the subject to absorb everything here in one gulp. That’s not necessary; in fact, it would be beyond the call of duty for most—aspiring test pilots aside. But do give the contents a quick initial pass, if only to get the measure of what’s available and how it’s organized. Your flights will be more productive if you know where to go in the texts for additional background. Before we fly together, I suggest that you read the section called “Axes and Derivatives.” This will introduce you to the concept of the velocity vector and to the basic aircraft response modes. If you pick up a head of steam, go on to read “Two-Dimensional Aerodynamics.” This is mostly about how pressure patterns form over the surface of a wing during the generation of lift, and begins to suggest how changes in those patterns, visible to us through our wing tufts, affect control. If you catch any typos, or statements that you think are either unclear or simply preposterous, please let me know. Thanks.

  • The Addition of Vortex Generators for STOL Performance and Or for Meeting the Light Sport Aircraft Rules ______
    __________________________________________________________________________ The Addition of Vortex Generators for STOL performance and or for Meeting the Light Sport Aircraft Rules ___________________________________________________________________________ This modification allows the Europa XS or Classic aircraft to operate with a greater stall margin and better low speed characteristics. For those owners operating out of very short runways or tight landing patterns requiring steep approach paths or slow speed maneuvering the addition of vortex generators (VGs) will improve safety margins. General Background: Aerodynamically, the Europa wing is capable of generating a 1.7 Cl or Coefficient of lift. This is used as a benchmark for aerodynamicists to determine stall speed. For the Europa XS this places the stall at approximately 49 Knots for the XS and 53 for the Classic aircraft (1300 lb gross weight for the Classic and 1370 for the XS). The differences between the stall speeds are due to the slight differences in wing area, gross weight and shape. VGs are small vertical fins attached at an angle to the airstream to the wing just aft of the leading edge of the upper surface of the airfoil. These VGs generate tiny vortices which thicken and add energy to the boundary layer allowing the wing to achieve a higher stalling angle of attack and thereby more lift, better aileron control and a lower stall speed. The positioning, spacing and angle of the VGs on the wing is critical for proper handling characteristics, pre-stall warning and stall speed reduction. This modification will provide guidance on the spacing and positioning necessary to achieve optimum handling characteristics to meet the builder’s desires.

  • Falco Builders Letter
    Falco Builders Letter A Visit with Frati If anybody ever suggests you go visit Frati “in Milan,” as Alfred Scott did when he heard I was going to be in Italy writing about the Piaggio Avanti turboprop, here’s my suggestion: get Alfred to pay the cabfare. If you can’t do that, buy a car. A small Fiat will do, and it’ll prob- ably be cheaper than a cab.

  • CFD Study of a NACA 63-415 Aerofoil Fitted with Stall Strips
    Ris0-R-137O(EN) CFD Study of a NACA 63-415 Aerofoil Fitted with Stall Strips Frederik Zahle, Niels N. S0rensen, Jeppe Johansen Ris0 National Laboratory, Roskilde September 2002 Abstract The present work describes a thorough investigation of 2D computa­ tions of the flow around a NACA 63-415 aerofoil fitted with stall strips (SS). A mesh study as well as a time step study is carried out and all computations are compared with experiments. Two different SS, 5mm and 7mm are investigated at several positions. Furthermore the influence of laminar to turbulent transition and the effect of a rounded SS were tested. There is not sufficient agreement between the experimental results and the simulations to draw any conclusions of optimum position and geometry of the SS. The 7mm SS’s placed at P00 and P-02 has the greatest effect on the max lift followed by SS P02. The 5mm SS’s does, as in the experiment, not change the lift curve noticeably. Even though this investigation does not conclusively suc­ ceed in verifying the experimental results with CFD, many useful conclusions can be drawn from the results. It is observed in the experiment that the vertical force fluctuates at higher an­ gles of attack. This indicates that small bubbles are being shed off the profile causing the force to vary. This property is observed when transition is included in the model and also when the tip of the SS is rounded. From this result it could be concluded that the level of turbulence produced on the tip of the SS is very important for the development of the flow downstream.

  • Surface Friction Disruption
    DAS Handling Enhancements SETUP Vortex Generators Thicker Control Surfaces Stall Strips 43 DAS Skin Friction Airflow Disruption Influence flow SETUP Air DEAD AIR Surface friction causes the airflow over the wing, tail, etc., to become stagnant and/or turbulent where the air comes into contact with the surface. As the airflow progresses aft, the turbulent boundary layer becomes progressively thicker and more unstable. Small control surface deflections within the area of turbulent air tend to produce sluggish and/or erratic responses, particularly at slower airspeeds. In order to begin achieving positive control, pilots must Traditional beveled control surface apply larger inputs to deflect the surface into smoother air, resulting in an exponential increase in the rate of response. Traditional beveled control surfaces further disrupt the already turbulent airflow as a result of the air tripping over the bevel’s sharp corners. The most noticeable aspects of flying with conventional beveled control surfaces are difficulties keeping the wings level, i.e, making Conventional non-linear control rate response fine adjustments, and response rates that exponentially speed up and slow down with airspeed changes -- thereby interfering with the High speed pilot’s ability to precisely predict the effects that his control inputs will have on the airplane. Full aileron Both tradition and ease of manufacture are the reasons that this deflection primitive design continues to be used. It’s also because of this design that many manufacturers have to resort to sealing the gaps to try to limit some of the airflow disruption and potential for flutter. 0 degrees Low speed per second 44 KPTR: Traditional beveled surfaces impair a pilot’s ability to predict how the plane will respond to commands.
