How to Make a Jetpack Backpack

Years ago, being able to fly was considered impossible. Today, you can ride a variety of aircraft, such as airplanes and helicopters. Other people usually pilot these while you ride as a passenger. Recently, the jet pack backpack has been engineered by various companies, allowing you to fly on your own. With this gadget, you are capable of gaining height by being pushed vertically and then forward. The highest speed possible is 50 mph.

Instructions

    • 1

      Cut and remove every piece of fabric from the backpack, leaving only the sturdy frame. Make sure it's as streamlined as possible. If not, cut the extra pieces.

    • 2

      Place the engine in front of the frame and move on to fit two double sprockets on the PTO end of your engine. Make sure the sprockets are firmly secured to the shafts and drill the mounting holes on the back of the backpack unit. The holes must be the same size as the bolts for proper fitting. Mount and bolt the engine to the unit and ensure that the bolts are tight.

    • 3

      Cut 36 circle pieces of the hard foam that are 1/3 inch round; make sure they measure 2 inches wide and 2 inches thick. Use the tape measure to measure this. These pieces will form the fan duct. After they are cut, stack each layer with epoxy until you have eight layers. Form a bell opening at the very tip of the duct. Insert the plywood and epoxy within the duct. Using the razor knife, cut pieces of 2.7-ounce fiberglass cloth and epoxy -- both the inside and the outside of the ducts.

      Drill holes on the shaft and mount the fans onto the hubs. Use the hammer to slightly pound on the sides of the fans to make sure they're tight. You may use spinners in order to enhance the productivity of the general fan system. The leading edges of the blades should overlap.

    • 5

      Make sure that all the bolts, nuts and blades are tight enough. If they aren't, use the hammer to push them slightly. Install the straps and safety harness by bolting them to the backpack frame. This should include a waist band, chest and shoulder straps.

      Install the fuel tank by bolting it securely below the engine. Attach the fuel pump on one end of the tank and on the other end of the engine.

    • 7

      Attach the jet pack to the chain by locking it to a stable object, such as a pipe. This is done when the unit is being tested for the first time in order to avoid accelerating too quickly or too high. If this happened, a fall could be fatal.
