Suppose a rocket is fired vertically upward with an initial velocity V0. 0000118000 00000 n They adjust variables and investigate how height and speed are affected. In this case, the maximum altitude of the rocket flying vertically is 357 m. If, however, the rocket deviated from the vertical at the highest point of its flight by only 5, then this altitude will be equal to 408 m. This is a 14 percent error! Physics and Math Behind the Model Rocket Flight, Table 2. This inclinometer can be used with both left and right hands. A model rocket on a launch pad is balanced and stays at rest because the force of gravity pulls it down and the pad pushes it up with exactly the same force (thats Newtons third law in action!). Various devices can be used to measure the angle between the rocket (or any other high object) and the ground. Remember, even if you dont know trigonometry yet, you can use this formula and a calculator with a button labeled tan to calculate the height of your rocket. In this formula, D is the distance between your position and the launch pad, and is the angle between the horizontal line and the line from your eye to the rocket. The calculator also shows that the maximum altitude is only 26 meters (85 ft). Estimate the maximum altitude and time to reach it for the Estes Amazon rocket with the Estes B4-4 motor and the 36 g onboard camera. Water Bottle Rocket Thrust - two calculation methods not matching, Optimal value of amount of water in a water rocket to fly to the highest altitude. Lets determine the height reached by another rocket. This gives a massive total thrust of 30.5 million newtons! At this time, the smoke charge burns without producing any thrust, only smoke. This allows it to orbit around the Earth. This velocity depends on the rockets weight and drag. }$This limit is called the escape velocity for the earth. Comparison to the OpenRocket simulation for the Estes Crossfire ISX rocket with the Estes C6-5 motor shows a 3.2% difference in the maximum altitude. There's probably no way you are going to be able to come up with a general equation that takes in all the different parameters this situation could have, but you can probably come up with something for a very specific case. This video shows how we built and launched this rocket. Make the pointer from a piece of 1.3 mm (AWG 16) wire 155 mm (6.10 in) long, bent in the middle as shown in the picture. Are there developed countries where elected officials can easily terminate government workers?

Example 1: Estimate the maximum altitude and time to reach it for the Estes Crossfire ISX rocket with the Estes C6-7 motor. In the latter case, markers must be placed on the ground. As for the angle between the rocket and the horizontal line, it cannot be determined with only one inclinometer. WebAnswer: The given speed, 2100 m/s, is a significant fraction of escape speed, and so even if the rocket has already ceased to propel itself and is in free fall, it will get high enough that gravity will thin significantly. Maximum height of the object is the highest vertical position along its trajectory. The object is flying upwards before reaching the highest point - and it's falling after that point. It means that at the highest point of projectile motion, the vertical velocity is equal to 0 (Vy = 0). From that equation we can find the time th needed to reach ), How can I create an equation that gives the maximum altitude of a water bottle rocket? The main source of errors is the angle between the vertical at the launch pad and the rocket at apogee. That means the thrust was almost two times less than the calculated one. 0000118031 00000 n As the propellant burns, the mass of the rocket decreases by the amount of the mass of gases leaving the nozzle. Radars can also be used to measure altitude. 0000098216 00000 n Let us look at an example. The comparison results are shown in Table 5. 0000126067 00000 n We will use two theodolites in another calculator to measure the maximum rocket altitude with much more precision. 0000005582 00000 n If you like physics and math, please continue reading. Taking into account the wind, this speed should be higher and the thrust-to-weight ratio should also be higher. After the motor burns out, the model rocket continues to ascend during the coasting flight phase. to find the maximum height requires calculus by the following: 1) find the derivative of G (t) or G' (t) 2) set G' (t) = 0 and solve for t.

Students investigate the motion of a rocket using a spreadsheet with graphs of motion included. 0.01 seconds will provide the precision that is sufficient for this calculator, especially considering the uncertainties associated with the performance of model rocket motors as well as other uncertainties that are not taken into account in these calculations. The pointer should rotate freely in the protractor hole. At this small speed, the rocket fins still do not work and the rocket is unstable and easily deviates from its vertical trajectory. According to Newton's Law of Universal Gravitation, the gravitational force on an object of mass$m$that has been projected vertically upward from the earth's surface is They measure not only the elevation angle of the rocket, but also a second angle from another theodolite to the rocket. The calculator will calculate the maximum altitude assuming that the rocket was flying perfectly vertically. In the real world, two phase flow exists as the rocket accelerates. This deviation from the vertical is the main source of errors in the measurement of the maximum altitude by this method. The maximum upward velocity the rocket will reach is vmax = (xmax - Bts) / 2A. b. : to reckon by exercise of practical judgment : estimate. : to determine by mathematical processes. The description of both formats is available on TrustCurve.org. WebTo calculate is to compute, by figuring out a mathematical equation or a situation. As the propellant burns, the rocket mass decreases, and its acceleration increases (if the thrust is constant). It is interesting to note that the propellant of the booster motor burned out at 2.57 seconds of the rocket flight instead of 1.6 seconds according to the C6-0 motor specifications. All day, VELUX ACTIVE monitors your home's temperature, humidity, and C02 levels and A clinometer is a simple version of a sextant, which also measures angles to locate the position of ships. Launching Safely in the 21st Century. 0000206334 00000 n To make our calculations, we will assume that the relationship between the motor thrust and propellant mass loss is linear the mass is decreasing with a higher speed when the thrust is stronger. There are several ways to predict the maximum altitude of a rocket. ** We require maximum skylight clearance dimensions in 1/4" increments (0, 1/4, 1/2, 3/4) for width and height. Web(a) A and B should have units of meters. It is a great book for those who have just started flying their first model rockets. TranslatorsCafe.com Unit Converter YouTube channel, Terms and Conditions As the water goes out, the mass of the rocket, the pressure of the air inside (which is undergoing an adiabatic expansion) and the acceleration all change. 0000144569 00000 n There is also the fourth force the lift force, which we will not consider here for simplicity because the downward drag force is usually much stronger than the upward lift force. This 5:1 ratio assumes a medium to long launch rod, good rocket stability, and no strong wind at the launch site. Vectors can be added to other vectors according to vector algebra, and can be multiplied by a scalar (real number).

You can use a theodolite if you can afford it, or you can use a simple device called an inclinometer or clinometer. The three forces acting on the rocket will also change. I'm starting Year 12 now, taking Math and Physics HL in IB but what I've learned so far still isn't sufficient to understand these sources. If you add a tripod disk with a bubble level and a full 360 chart or a camera pan base (about 15 dollars with shipping on Ali) and install your device on a tripod, you will get a simple theodolite that can measure the inclination and azimuth angles. You can then pick an initial combination of water volume and pressure, shoot off the rocket and record the height. You can view a video of an unsuccessful launch with this motor. Study with other students and unlock Numerade solutions for free. a) Calculate the maximum height above the ground reached by the model rocket. This means that, every second, the speed of the rocket increases by 90 m/s. This is a differential equation because acceleration is the second derivative of position with respect to time. Both formats contain the basic information about the motor as well as its thrust curve in the form of its data points. The distance between the lugs is 13 cm. On a windy day, this velocity must be higher. To measure the angle to the rocket at its maximum altitude, sight the rocket through the clinometers straw, hold the plumb string or the pointer with your finger and read the degrees where the thread or the pointer crosses the arc of the protractor. Before proceeding with our calculations, we will talk about where to get the information describing the dependence of rocket model motors thrust on time. Nose cones were tested on the same model: 1st stage propellant burns out, booster apogee, 2nd stage ignition, The rocket movement stopped; the camera was separated from the rocket. We work hard to ensure that the results presented by TranslatorsCafe.com converters and calculators are correct. Initial Velocity: Cross Section is Earth's radius, and gis the acceleration due to gravity: Also, by Newton's Second law; F = ma = m d IgR? No need to obtain the solution analytically as the polynomial is not straightforward. A clinometer is an instrument used for measuring the inclination of the instrument relative to the vertical or horizontal axis. I already know that the max height is 281.66 m. Thank you!
