I would like to know a initial launch radius and velocity vectors after the orbiter first establishes a ballistic orbit of a typical rocket launch (Space Shuttle, Saturn V, etc). R = (rx)*i + (ry)*j + (rz)*k V = (vx)*i + (vy)*j + (vz)*k i - Direction of the Vernal Equinox j - Righthand rule 90...

At the Apogee I have a radius (rx,ry,rz) and a velocity (vx,vy,vz). I want to expand the ellipse using Hohmann Transfer. v=Math.Sqr(vx^2+vy^2+vz^2) uv=(vx/v,vy/v,vz/v) Here is where my delema is: vNew is the desired instantaneous velocity which will keep on the same plane you must...

I would like to know how to find a acceleration perpendicular to the center of mass for an object traveling in a RA and DEC direction at an arbitrary angle away from the perpendicular to an object. I want to know this to be able to produce a Roll with a constant vectoring of the engines to...

Looking for Air Drag Coefficient, Cd, and the Surface Area, A, for the Space Shuttle, Saturn V and other rockets so I can calculate the Air Drag Force on the Shuttle. I know the Air Density as it varies with km height. density @sea level is about 1.2kg/m^3...

I am trying to make a computer model of a Space Shuttle launch. Wikipedia give some data but does not give a path to follow. Any more comprehensive sites would be helpful. Here is my math: MN = 1e6 * kg * m / s^2 = 1e3 * kg * km / s^2 acceleration = Force(in MN) / Mass (Is this...

Is a Rocket tilted South in the Northern Hemisphere Launch Site due to the Geocentric Latitude and Geodetic Latitude being different? Would there be no tilt at the equator because LATGeo = LAT = 0 neglecting the wind?

When Holmann Tranfer occurs is it only at the APO or the most distant part of the elliptical orbit? Does a spaceship have to vector the rocket it stay on the path of that ellipse?

I have made a model using the Gibbs Method. This way uses three radius vectors or three radii, right ascensions and declinations. I am having a difficult time locating a large string of data in order to plug them into my equations. Can someone help?
