How to buy NPNT drone in INDIA

 HOW to buy NPNT Drones in INDIA?

Drones  hаve never  been аs ассessible  оr аffоrdаble as they  are now – so it's а greаt  time tо invest in а new аeriаl  соmраniоn. With fаst-imрrоving саmerаs,  gimbаls, battery lives and аutоmаted flying  mоdes, drоnes hаve quite literаlly tаken оff  in the раst few yeаrs. Рhоtоs and videos that  once demanded niche рrоfеssіоnаl equipment are now  possible fоr the рriсe оf а DSLR оr mirrоrless саmerа.

But  drones  haven't been  withоut there соntrоversies  either. You may have seen some  high-profile cover аge оf the India's   drone mаnufacture , (idea forge , Asteria aerospace, throttle aerospace, hubble fly etc including all manufacture listed on digital sky portal) ,  аnd its sоmewhаt tense relаtiоnshiр with the DGCA and QCI gоvernment agency reсently.  

Fоr  drоne  buyers, in India had confusion of buying NPNT drone as gоvernment had made  deсisiоn tо make NPNT mandatory for all manufacture listed in lis at digital sky portal. Flying  drоnes, hоwever, will nоt be аs simрle аs buying оne, whiррing it оut аnd рilоting it  intо the аir whenever аnd wherever yоu wаnt. .

DGCA drone manufacturers need to have approval for NPNT from QCI  .certified drones would have permission to sell drones and have NPNT approved symbols on their drone. Faking and failing will  be punishable offence as per new gazette 

Drone operations in India will be controlled by a licence-permission system quite like the regulations that govern driving cars.Just like a driving license, you will need an Unmanned Aircraft Operator Permit in order to pilot a drone. Similаrly,  yоur drоne, like yоur саr, will need tо be registered with the gоvernment аnd will be issued with а Unique Identifiсаtiоn Number.

As a working lot in the UAV Industry many drone enthusiasts and professionals have asked me the same question again and again . begin to be an expert in the UAV Industry in India . drone laws has made strict and their cost and quality has been made to meet international standard however my study show some stats that 70-80 % component of drone out sources and assemble in India in name of “MAKE in INDIA”  initiative however still as per new laws update by DGCA made that every manufucture will need QCI approval to get manufacturing certificate in INDIA .

The questions were asked to me again .

Do those companies who are listed on Digital sky platform really have NPNT ?

And answer to that is NO , let me explain AS per the new update law all manufacturers need to get a manufacturing certificate from QCI . so than how they were listed in Digital sky portal .

Initially they were given provisional approval hence they  made it in the list however QCI has told and had been warning them that if you don't NPNT certified then you are not legal to manufacture of NPNT drone.

However many of have ignored these warning and still have used NPNT approved on their website and their letterhead and if they continue they would be fine as per new amendments 

So how to buy a NPNT drone in INDIA from a manufacturer ?

99 % manufacture will be demonstrated above in theri demo . And still if everything is good as per requirement how to have NPNT DRONE?

ALways asked for following document to manufacture while buying drone

If the above manufacturer failed to produce then that drone is not a NPNT and you are dealing with fake ones . Even most manufacturers give you in writing on their letter head that this drone is NPNT, do not believe in that it is fake and no authentication hence i request who buy the drone must check paperwork  and technical specification of drone while buying or hire a professional to give you proper guidance.

I hope this helps you to buy a proper drone as per requirement. Well this was i can share with you guys now for please contact any further discussion of points i guess help to run drone business smoothly .

There is interesting UAVs that use flapping wings to fly like a bird. The details of the physics and aerodynamics of flight using flapping wings are beyond our scope, but the basic aerodynamics can be appreciated based on the same mechanisms for generating aerodynamic forces that we have outlined for fixed wings. The flapping of the wings of birds is not a pure up and down or rowing backstroke as commonly thought.

While designing such UAVs made such observations that can help to understand the concept on a omkar pande brid aerodynamic review similar projects. The wings of a flying bird move up and down as they are flapped, but they also move forward due to the bird’s velocity through the air mass. Shows the resulting velocity and force triangles when the wing is moving downward. The net velocity of the wing through the air mass is the sum of the forward velocity of the bird’s body (V) and the downward velocity of the wing, driven by the muscles of the bird (w), which varies over the length of the wing, being greatest at the wingtip. The resulting total velocity through the air mass is forward and down, which means that the relative wind over the wing is to the rear and up.

The net aerodynamic force generated by that relative wind (F) is perpendicular to the relative wind and can be resolved into two components, lift (L) upward and thrust (T) forward. The velocity and force triangles vary along the length of the wing because (W) is approximately zero at the root of the wing, where it joins the body of the bird and has a maximum value at the tip of the wing, so that the net force, (F) is nearly vertical at the root of the wing and tilted.


Furthest forward at the tip. As a result, it sometimes is said that the root of the bird’s wing produces mostly lift and the tip produces mostly thrust. It is also possible for the bird to introduce a variable twist in the wingover its length, which could maintain the same angle of attack as (w) increases and the relative wind becomes tilted more upward near the tip.

This twist can also be used to create an optimum angle of attack that varies over the length of the wing. This can be used to increase the thrust available from the wingtip. The above diagram shows how flapping the wing up and down can provide net lift and net positive thrust. The direction of the relative wind is tangent to the curved line that varies over the up and down strokes. To maximize the average lift and thrust, the angle of attack is selected by the bird to be large during the downstroke, which creates a large net aerodynamic force.

 This results in a large lift and a large positive thrust. During the upstroke, the angle of attack is reduced, leading to a smaller net aerodynamic force


This means that even though the thrust https://drone2495.blogspot.com/  this is now negative, the average thrust over a complete cycle is positive. The lift remains positive, although smaller than during the upstroke. The bird can make the negative thrust during the upstroke even smaller by bending its


Wings during the upstroke as shown above diagram.This largely eliminates the forces induced by the outer portions of the wings, which are the most important contributors to thrust, while preserving much of the lift produced near the wing roots. This simplified description of how flapping wings can allow a bird to fly is a far as we are going to go in this introductory text. There are some significant differences between how birds fly and how insects fly, and not all birds fly in exactly the same way. In the early days of heavier-than-air flight, there were many attempts to use flapping wings to lift a human passenger. All were unsuccessful. As interest has increased in recent years in small, even tiny, UAVs, the biomechanics of bird and insect flight is being closely re-examined and recently have been successfully emulated by machines in the field of UAV.
