Presentation Transcript

    4. Acceleration, Time, Distance F = ma Vf = V0 + at s = V0t + at2

    5. Vector Addition

    6. Trigonometric Functions

    8. Specific Heat Specific Heat : the amount of heat that enters or leaves a unit mass while the substance changes one degree in temperature. c = Btu per lbsm - degree Rankine cp : specific heat at constant pressure cv : specific heat at constant volume k : ratio of specific heats

    9. Specific Impulse

    10. Launch Velocity Losses Gravity losses Pitch over to get correct velocity vector alignment for orbital insertion Drag from atmosphere Not instantaneous application of velocity

    12. Three Stage Booster

    13. ORBIT FORMULAS

    17. Coordinate Systems Cartesian Coordinates Abscissa = x Ordinate = y (x,y) Polar Coordinates Radius Vector = r Vectorial Angle = q (r,q)

    18. Description of Orbit Right Ascension Measured eastward from the vernal equinox In Spring when the sun’s center crosses the equatorial plane once thought to be aligned with the first point of the constellation Aries Inclination Argument of Perigee Two of the following Eccentricity Perigee Apogee
