Model airplanes powered by compressed air ? Anyone ?

In summary, the conversation discusses the idea of using compressed air to power model airplanes. The potential viability of this idea is questioned, and calculations are suggested to determine the required volume of air and weight of the model. It is also noted that compressed CO2 has been used in the past for similar purposes, but weight may be a limiting factor in this experiment.

Model airplanes powered by compressed air ...?? Anyone ??

Hello,

Has anybody explored idea of powering aeroplane models by compressed air?

Does this seem to be viable idea?

Prima-facie:

Let's say a rubber tire tube (old days of car tires - now its all tube less) inflated to say 60 PSI with controlled aperture of 2.2 mm - valve operated - will exert force of 1.57 N (pls correct if wrong ; i have used simple formula : F = Pressure X Area)

Assuming the weight of model 200 gm this force would be sufficient to bring it in motion? can anyone help in calculating volume of tube required for this experiment?

Regards
Shashank

I remember model airplanes being propelled by compressed CO2, so your idea doesn't seem that weird.

Biggest issue is weight. You would need an aluminum or steel container to hold the pressurized gas to get an appreciable amount of thrust to fly your model. Not to mention you may need a regulator too if you want to control the flow rate. It might be fun though to watch it blast off for a few seconds!
 

1. How do model airplanes powered by compressed air work?

Model airplanes powered by compressed air work by using a canister of compressed air, typically carbon dioxide, as a power source. The air is released in a controlled manner through a valve, creating thrust that propels the airplane forward.

2. What materials are typically used to build model airplanes powered by compressed air?

The materials used to build model airplanes powered by compressed air can vary, but often include lightweight and durable materials such as balsa wood, foam, or plastic. Some models may also incorporate metal components for added strength.

3. Are there different types of compressed air model airplanes?

Yes, there are different types of compressed air model airplanes. Some models use a single canister of compressed air, while others use multiple canisters for increased power. There are also models that use a rubber band to store and release compressed air, known as rubber-powered airplanes.

4. How far can model airplanes powered by compressed air fly?

The flight distance of model airplanes powered by compressed air can vary depending on factors such as the size and weight of the airplane, the amount of compressed air used, and external factors like wind. On average, these model airplanes can fly up to several hundred feet.

5. Are there any safety precautions to take when handling compressed air model airplanes?

Yes, it is important to handle compressed air model airplanes with caution. The canisters of compressed air should be handled carefully and stored properly to avoid any accidents. It is also important to follow instructions carefully and never aim the airplane at people or animals.
