AERIAL TARGETS

Aerial targets are those targets which are used by ground based guns, naval armament fitted on ships or guns fitted on attack helicopters or airships. 

The factors that govern the aerial targets are mostly the requirement of the gun or armament mounted on ships, land based systems or attack helicopters.

There are many aerial targets available like Banshee or NGAT they are propelled by turbine engines or are drone based. 

There are not many aerial targets when it comes to gun as the gun requires the target to be big enough to be capable of getting captured by a suitable camera! Only then it can be effectively  tracked and fired upon. 

Swaman Achuk has a solution for such an aerial target - ACHUK

 

ACHUK

OTHER TARGET

Target size bigger (Approx 3 times)

Target size around 10 ft x 18 inches

Target speed less  - VMAX 100 kmph and VBE 75- 80 kmph

Target speed aprox 75 - 100 kmph

Less probabilities of multiple reflections due to bigger target size

Multiple reflections due to smaller target size

More probability of getting laser returns due to bigger target

Less probability of getting laser returns due to smaller target and difficulty in acquiring

AGL upto 150 m

TREE TRUNK - SUCCULENT PLANT DISPLAY















A cut tree trunk was spotted while driving. 



White ants had made their home inside the trunk and made it hollow. I picked it up. It was cleaned and was treated with anti termite spray. 


The tree trunk was varnished, polished. 



A 10 mm thick glass was fitted on top of the trunk with rubber vacuum holders.








 

The hollow part was used to lit up with an electric bulb. 




The abondand tree trunk was transformed into a Succulent Plant Display. The succulent display is by the better half  who develops and takes care of the garden.

GARDEN CHAIR WEAVING (PARACHORD OR PLASTIC WIRE NETTING)

This was the chair to be salvaged. 






The old netting was stripped out. It was cleaned and and painted with a coat of black paint.  


A para chord was bought (it comes by weight and cheap - around 200 rs per kg). It is wound on a make shift bobbin. This bobbin is important so that it can be meshed back and forth with ease. 



Before the meshing, a black parachord was wound at four courners of the base and back to make the area a rectangle so as to make meshing easy. Every where a constriction knot was used to have a firm long lasting knot.  




Once the corners done, the white parachord was meshed in a manner to have the chord running over the back base pipe and under the back base pipe evenly so as to get a tight base. 


The bobbin came handy to work swiftly without parachord getting entangled while going over and under the base and back pipes. 


The scale was used to separate the over and under para chords. so that the cross black para chord could be woven back and forth easily.





The result is here!! 
Cost of new chair - 3000 - 3500 rs
Cost of old chair given to refurbish (for weaving only!!)  - 2500 rs
Cost of old chair if refurbished at home (as hobby)  - 250 rs.

You have to decide how you are going to spend your time. 

I prefer the third option (critics will always roast me for not contributing to the nations economy though !!!!!)
