Model Rockets - Is there a Market for them in India?

Hi,

Model rocketry is a popular hobby in many countries around the world. Unfortunately this exciting hobby seems to be nearly non existent in India even though we have a number of space, rocket and aeromodelling enthusiasts here.  There could be many reasons for this but one of the biggest stumbling blocks appears to be lack of availability of rocket kits, components, motors etc over here.

I was wondering if you think that there is a demand for such  rocket kits, components, motors etc India and what would be the expectations of people over here. Any comments or suggestions in this regard would be appreciated.

Thanks Smiley

That is correct.
1) The models which I am referring to are significantly more powerful than the diwali kind of rockets which will make them go higher and faster.
2)They will have a parachute recovery system and be reusable.
3) They will have a electrical launch system and will not be fuse lit like diwali rockets.
4) The rocket motors will be changeable for varying power and other parameters.

1. Much much more powerful.
2. A parachute is a must, These rockets come down as fast as they go up.
3. My ones were fuse lit. A very long fuse.
4. Just like model planes.

its just diwali fireworks LOL
http://www.estesrockets.com/rockets/ here is the site

The Diwali rockets that you have used are entirely different from the rockets that estes makes and there is no similarity between them except that they use the same basic physics principles. Please read more on the rockets that estes offers.


your right but we need black powder mixture of aluminium powder,ammonium perchlorate,potassium nitrate.but for these chemical we need special permission from govt

1) The motors (motors power the rocket) will be factory made. There will be no handling of hazardous chemicals by the user. The user will not make the motors except to insert the electrical igniters in them before launch.

2) The rockets will come in ready to use form or in form of kits in which the user will have to make the rocket body, recovery system etc.  The kits could be of varying complexity depending upon user skill.

@Cosmonaut

typed diwali fireworks for fun.

There are home made rockets in Tamilnadu used for display in marriage and temple function which is illegal and sound level is more than 125db.

these home made rockets comes in steel pipe and no fuse just hand launch high risk many people have lost their hand.


Rocket theory is not rocket science.

as you said motor power rockets and There will be no handling of hazardous chemicals by the user?then how come smoke and flame produced does they have turbine engine?

here is the link

http://en.wikipedia.org/wiki/Model_rocket  clear picture what we need and what substance we need.

Motor power means don't imagine like RC motor.100% you need black powder.

These black powder react according to compression you fill in motor.High compression filling some time lead to explode.like cannon

if you order online you will get physical body and other launching device. But end of day fuel is black powder.

Getting black powder in india equal to flying on pegasus

A little knowledge is a dangerous thing.

I don't know where the above came from. Afaik, Black powder is Charcoal, Potassium Nitrate and Sulphur and I have researched this subject and manufactured it at home for the last 20 years. Both fused and mixed. Rocket candy is a different process with Sugar and Potassium Nitrate (with some Red Oxide powder) fused at a high temperature. All chemicals were bought from laboraory supplies shops with legitimate cash memo inclusive of sales tax and vat. What 'special govt. permission' are you talking about?

Cosmonaut, I am keen. Keep in touch.

Regards.

Mr. Moorthy, it is obvious that you have absolutely zero knowledge about Model Rocketry. I am sorry if I sound scathing, however, it is one of my favourite subjects and my rockets have been rather successful - both Black Powder and Rocket Candy. For your information, some of my students in Shillong, Meghalaya have been launching their own recoverable rockets for quite some time now. They use Black Powder and Rocket Candy propellants. There has not been single minor (or major) injury so far.

Perhaps, you would like to visit this site and gain some thorough knowledge on Model Rocketry. Richard Nakka is an internationally acclaimed authority on the subject.

http://www.nakka-rocketry.net/

There are other forms of Model Rocketry which don't need any combustion like Pneumatic Rockets and Water Rockets. More on that later.

Well actually it is something like a engine on a RC plane. Most aeromodelling enthusiasts do no make their own engines whether it is electric, gas, glow, nitro or even rocket engines. What they do is they buy the engine separately and then attach it to an aircraft body that they have built. The same applies to model rockets. People buy the engines (called rocket motors) separately and attach it to the rocket body that they have built.

From the same Wikipedia page that you have linked, I urge you to see some examples rocket motors used in amateur rocketry:

http://upload.wikimedia.org/wikipedia/commons/thumb/4/43/Model_Rocket_Motors.jpg/388px-Model_Rocket_Motors.jpg
Model Rockets - Is there a Market for them in India?


These are factory made disposable motors that contain all those chemicals and are ready to fire. You just have to attach then to the rocket you have built and fire them. There is a lot more to a rocket than just the motor.  

You dont have to worry about dangerous chemicals and all and neither do you require a license to use, transport or store small quantifies of these for personal use.

BTW, all rocket motors are not made out of black powder. The big black motor that you see on the right side of the image is made using composite propellant.

------------------------------------------------------

 @VC many thanks for the reply. I am getting a feeling that it wont be a case of just selling kits/components but also educating people about model rocketry here from zero. This is probably going to be a uphill task

Mr. Moorthy, Black Powder is NOT 'available'. It has to be 'manufactured'. I will deliberately not give out the percentage mix ratios here. That is my prerogative.

Rockets are banned almost everywhere, especially in North East India. So are Deepawali crackers that are suspected of causing sound pollution beyond the permissible auditory limit. However, they are sold openly when the season arrives.

I have interacted with manufacturers of rockets and learnt the techniques from them at Nungi, West Bengal and Barpeta, Assam since 1991. Sir, I have a little knowledge, however, I assure you that it runs deep.

Black powder can be used to make many items required for pyrotechnics, like fuses, propellants, lift charges, gunpowder and many more. It all depends on ratio and manufacturing process.
For rockets which are launched during the day sugar based propellants are quite  popular.
As far as purchasing rocket motors, I feel making your own works out much cheaper.
