RangeGames can record your answers for teacher evaluation, or you can just play for fun. RocketModeler: This program lets you design and study the flight of a model rocket.
You can vary the size of the rocket, the number of fins, and the materials used to construct the rocket. You can choose from a variety of available model rocket engines and test fly your rocket on the computer. The program computes the stability of your design and the flight trajectory. Output includes the maximum altitude which the rocket achieves. You can then compare the computed and actual performance of your model rocket.
KiteModeler: This program lets you design and study the flight of a kite. You can select from five different types of kites and then vary the length, width and types of materials used to construct the kite.
You then trim the kite by setting the length of the bridle and tail and the position of the knot attaching the control line to the bridle. Finally, you test fly your kite on the computer by setting the wind speed and the length of control line. The program computes the aerodynamic forces, weight, and stability of your design and the shape of the control line as it sags under its own weight.
Output includes the maximum altitude which the kite achieves. You can then compare the computed and actual performance of your kite design. SoundWave: Using the SoundWave applet, students learn about sounds and how they are transmitted through the air. A "bug" emits a sound that is detected by a microphone. Not all the details of the LS7 engine could be obtained, such as the actual piston valve relief depths, so the clearance information is for display purposes only, but as entered this display shows sufficient intake and exhaust piston to valve clearance.
Fortunately, the valve relief depths are available on pistons you buy from the manufacturer. More information on what is acceptable for clearances is presented later.
Once the Piston to Valve Clearance calculations are complete, a plot GUI shows up with the first plot selections available for analysis. This displays how the program estimated the complete lobe profile from the points entered using the spline fit generated by the program. It includes all the parameters entered including the deck height, head gasket thickness, piston valve relief's, etc.
Recommended minimum clearance depends on engine inertia, materials used, and temperature effects, but I have seen it as low as 0. I would recommend a little more, but certainly the value given below of 0.
You can play with the head gasket thickness, cam timing, block deck height, and other related parameters and see this change. I have seen values as low as 0. Certainly the value given below of 0.
It also shows the lobe separation and valve overlap. Valve overlap contributes to the intake and exhaust flow dynamics throughout the RPM range. Reducing the lobe separation, increases the overlap, reducing intake and exhaust efficiency at lower RPM, but increasing efficiency at higher RPM. Now we can hit the Dyno Performance button. Data will again be written to the simulation window, including the estimated static connecting rod to camshaft clearance.
Here the value is 0. Consensus is that a clearance of 0. Also shown is the compression test pressure, which for the LS7 is estimated here close to the actual of about psi. The starter cranks the engine over a few revolutions to determine the test pressure, then fires normally based on the ignition timing until the RPM reaches the maximum, which can be entered as high as The time displayed is the simulation or engine time in seconds at full throttle under load on the dyno.
Due to the extensive calculations, this run to RPM took about 5 minutes with the simulation. It includes internal friction losses, but not engine accessories, intake filters, exhaust mufflers, or drive train losses in transmission, rear end, and wheels. When using this tool you are given the full force of a AAA tool. Game developers of this free slot games website have used Unreal to develop the slot machine games.

Honorable Mention: Amazon Lumberyard. Lumberyard is a relative newcomer to the game engine space. All of the engines we recommend are fully documented and come with a slew of tutorials online.
Compelling art is the make-or-break point on whether a new player will be willing to try a new game. GIMP is a freely distributed program for image authoring, graphic design, and photo manipulation. Use GIMP to start your game art. Check out a world of tutorials on the web. Further development of OpenVSP software will stimulate economic opportunity in aviation and aerospace.
Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. Who is FreeCAD for?
