But we from Mejzlik side can guarantee you that the tool is safe and there will be no security breach using this tool. There might be some problem if your company does not allow you to download it for security reasons. The tool has some macros running in the background. 7 hours ago &0183 &32 At that time, the controlled descent of the lander ceased, and it is believed to have free-fallen to the Moon’s surface. The calculator file consists of a basic description, user manual, calculator, and the result (in both numerical and graphic form). We will also extend the calculator with electric propellers soon. The calculation is based on simulated performance of different Mejzlik two-bladed gas propellers and we intend to replace this data with wind tunnel measurements to make it even more accurate. The calculator also allows you to try different propeller geometries to find the closest off the shelf solution for the initial flights. The dynamic calculator does not tend to replace the simulation process for the optimization or customization, it rather is a quick tool to get the rough predicted performance. Please remember that the main goal of this dynamic calculator is to present how does the performance/efficiency of the propeller changes for different parameters (diameter, pitch, airspeed, thrust, density, etc.) and flight phases (cruise, climb). You can find a downloadable excel sheet named Dynamic Thrust Calculator. ![]() Sometimes the resulting turn-off switching loss is so low that the result is displayed as zero.You will be able to download the calculator for free in the Technical data tab of our home page. Again, because the output capacitance energy is recycled, the turn-off energy in circuits with ZVS turn-on is calculated as the difference between the datasheet (hard switched) turn-off energy E off minus the output capacitance energy corresponding to the switched voltage. It is however possible to measure the output capacitance and therefore to calculate its energy stored after turn-off. It is impossible to measure these currents separately during turn-off only the total is measured and used in turn-off energy calculations of the datasheet. Propulsion Speed (Ground Speed) for Constant Load Propulsion speed vs. We will have to change our methods of propulsion completely. During turn-off, some of the drain current flows through the FET channel and creates heat, while the remainder of the current charges the output capacitance. The graphs below were plotted directly with the drag calculator programme. Delta-v is produced by reaction engines, such as rocket engines, and is proportional to the thrust per unit mass and the burn time. The question is simply when Many new technologies will need to exist. Range of a Projectile is nothing but the horizontal distance covered during the flight time. This is different from hard switching where output capacitance energy becomes lost (as heat) in the FET as it switches on. In circuits with zero drain-source voltage turn-on (ZVS), this output capacitance energy is recycled to the load and/or input capacitance. When a FET turns off and voltage across it increases from near zero to its steady off-state voltage, energy is stored in the output capacitance.
