Small gliding Planes

26 May 2023

I glued a piece of folded cardboard over a styrofoam fuselage blank for nose weight. Then the colour profiles were glued first to one side, trimmed the foam/cardboard and then the other side. A small slot cut at bottom for hooking on a rubber band.

Blow through a launcher tube and the plane shoots out. It's a blow powered glider. This is not new, decades ago, some modellers have devised and flown such models. Let's hope that we are not spitting saliva.

A length of plastic straw (or rolled paper tube) has the front capped and is affixed to a model. A blow pipe which fits inside the previous straw and by blowing into this blow pipe, the model is propelled forward.

The article I read has the straw longer than the length of the model. I think the straw can be shorter because I don't think a very long length helps to propell it further or faster.

I think a modular system is good fun.
  • Find 2 plastic straws, one fitting smoothly over the other. The bigger straw is the one to be glued to the model and the smaller straw is the blow pipe.
  • Cut a few 3-5 cm length of straw with a foam or balsa cap glued on one end. 
  • Model is made from thin paper (printed or unprinted): cut the planform and glue the side profiles.
  • Strip of paper glued around the straw and the ends glued to the bottom of the model.
 Don't hyper-ventilate, don't spit and be civil.
