    Hi all,

    File: Aircraft Performance, limited with rectangular wings and 2 bladed props, no taper at all,
    contains
    Basic aerodynamics ,
    Static thrust,
    In flight thrust
    Tail preliminary sizing
    Takeoff ground roll
    Rate of climb
    Range
    Neutral point, power effect is not considered because it shifts the NP only by 3 percent,
    Elevator sizing, (downwash needs to be ironed from Naca report 648)

    All metric

    In Hamilton sheet u will find a static thrust curve ( vertical axis is Ct/Cp, Thrust and Power coefficients) for 2 bladed props having a Blade Activity Factor of 80, I pulled out this curve from Hamilton's Generalized Method of Propeller Performance Estimation for GA Aircraft, this article can be downloaded from NTRS server,

    File: Flaps

    Valid for rectangular wings, plain flaps, can be partial, i digitized curves from The Aerodynamic Characteristics of Flaps by Young which is available in Aerade server, data will be entered into B60,62, 64 and 66,

    I wrote these files in IOS Numbers and converted to Excel, so the files come with unprotected cells and lost red colors of data input cells, no macros,if you use it try not to enter data in cells containing formulas

    The thread didn't allow me to upload the files directly so i had to upload them into my dropbox and give the links here,

    Thanks rapidshot.

    MODERATORS: Consider a section where design spreadsheets can be saved and accessed for download by HBAers.

    I routinely upload .xls files here.
