Launcher Definition and 117 Threads

A grenade launcher is a weapon that fires a specially-designed large-caliber projectile, often with an explosive, smoke or gas warhead. Today, the term generally refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, although larger crew-served launchers are issued at higher levels of organisation by military forces.Grenade launchers can either come in the form of standalone weapons (either single-shot or repeating) or attachments mounted to a parent firearm, usually a rifle. Larger crew-served automatic grenade launchers such as the Mk 19 are mounted on tripods or vehicles.
Some armored fighting vehicles also mount fixed arrays of short range, single-shot grenade launchers as a means of defense.

    Distance problem, Using Launcher need to find objects distance

    Hows it going guys, I need to now how to find distance of an object without actually shooting from my launcher. I have that it shoots 518.28 feet per sec ( initial velocity) ends at 0 ft/s (final velocity), that gravity's constant is -32.15 feet/sec2(9.8 meters/sec2), I also have that it shoots...

    Projectile Motion assignment - Building a projectile launcher

    I need help/advice on building a simple projectile launcher, for a tennis ball or smaller object. I need to calculate the angle so it must be something that shoots fairly straight (ballista?). Any links or advice on this would be much appreciated ~Hans

    How Do You Calculate the Launch Speed of a Ball in a Pinball Machine?

    The ball launcher in a pinball machine has a spring with a force constant of 1.10 N/cm (Fig. P5.71). The surface on which the ball moves is inclined 10.0° with respect to the horizontal. If the spring is initially compressed 4.00 cm, find the launching speed of a 0.100 kg ball when the plunger...

    Construct a Launcher Under $25 with PVC Pipes

    My engineering assignment calls for me to create a launcher that will propel a jumbo marshmallow at a target 50 feet away. I’m really excited about this assignment since this will be the first thing I’ve ever constructed on my own, but I’m unsure about finding inexpensive materials (my launcher...

    How Do You Make A Ping Pong Launcher?

    Hey. :) I'm new here and this is my first post... so please bear with me... xo I'm a 4th year high school and we're going to have an activity in Physics tomorrow. We need to make a ping pong launcher that will make the ball stay in the air for the longest period of time. Here are the...

    Building a Projectile Launcher: Rubberband, Spring or Catapult?

    I have a question- How exactly should I go about building a projectile launcher with a ping pong ball?:rolleyes: Would you recommend a catapult launcher, a rubberband launcher, or a spring launcher? Thanks.

    Help! Egg Launcher Project for High Schooler

    Not sure if this is the right place to post this, but will give it a shot. I am helping out my little sis this weekend as she has an egg launcher project for high school. There are weight and dimension limitations of course, and I'm not quite clear on other rules (when I took this class ~8...

    How can I calculate the range and trajectory of a ping pong ball launcher?

    Hi there. I'm at bath uni. Our group is building a ping pong ball launcher. Here are some issues we encountered. If the ball is to drop vertically into a 40mm tube with air flowing at 6bar(does this mean anything?) will it drop in or will it blow back out. Also I'm not to sure how to...

    Class Project: Moustrap Launcher

    In my physics class, we recently got assigned a project that deals with moustraps. More specifically, we have to use two (2) mousetraps to shoot a starburst the farthest distance possible. You can only use the mousetraps tho, what do u think would be the best way to harness the most energy of a...

    Maglev launcher for suborbital space tourism?

    Hi, I'm not an engineer nor a scientist, but I'm fascinated by maglaunchers and I have a few questions about them which maybe you could answer. -I read that maglaunchers are being studied to accelerate spacecraft in a first phase, in order to reduce or get rid of the first stage of the...

    Work and friction in a mass-spring launcher

    I have my Physics final tomorrow morning so I'm doing some last minute review and I just need someone to check if I have this sample problem done right. A spring having a force constant of 2500N/m is placed around a vertical rod as shown (I don't have an electronic copy of the picture). A...

    Tennis Ball Launcher Project Calculations

    I am building a tennis ball launcher for my physics class, and it needs to be no bigger than 1m X 1m, it must reach to a target that is 2 - 7m away from the launch site, and the target may or may not be at a certain height. No fire, explosives, gasses may be used. It must run on pure mechanical...

    Can a Mattress Spring Increase Tennis Ball Launcher Velocity?

    Me and two friends need to build a tennis ball launcher using nothing but stored mechanical energy to propel it. Our concept is similar to a mortar or cannon. We tried some comercial springs from Home Depot and even a spring from inside a sprinkler head, but the tennis ball does not have enough...

    Unique Launcher Ideas for Lisa's Physics Project

    Hi there! My name is Lisa, and I live in the Netherlands (where school has already begun 2 weeks ago ). I have a pretty urgent question concerning a physics project. I need to think of a certain construction which launches an arrow/ dart arrow / marble from a variable angle. It's very...

    Building a Spring Launcher: Attaching the Spring

    i need to make a spring launcher that launches a small ball using a spring (one that stretches)... so how do i attach the spring to the piece of wood so when i stretch it all of the energy is converted to the ball..
