D.C. Enterprises Through The Years
Established in 2001 as a proprietary Small Scale Industry
Development and marketing of electronic devices and components used for safety measures in household and industry/Defense communication components, innovatively designed electronic equipment for MRO in industry
Current activities include the development of state of the art propulsion and control component technologies for sub miniature flying robot applications weighing less than 5g and having a span of 75mm and below, and VTOL entomopters.
Indigenous development of Sky Scope Mark I and II quadrotors.
Indigenous development of brushless camera gimbals
Developed India's first hovering 125mm span flapping wing Micro air vehicle under the National program for Micro Air vehicles: • 125mm span • 5gms All up weight • Endurance of 5 min • Carries a small camera payload • Composite construction
Developed the worlds smallest 3 phase brushless outrunner motor weighing 250mg, under the National program for Micro Air vehicles for future Nano air vehicles SIATI award for excellence in indigenisation and development of aerospace technologies. Designed and developed a 300mm class Micro Quadcopter for the National competition in Micro air vehicles. The "silver arrow" won the competition and fulfilled all mission requirements.
Developed India's first Vertical Takeoff and Landing (VTOL) flapping wing Micro air vehicle under the National program for Micro Air vehicles: • 18gms All up weight • Can Hover in one location • Carries a 2gm Camera payload • Endurance of 18mins • Complete composite construction • Composite moulded gearbox and gears Developed a 2Kg class Mini Air Vehicle for the Low Intensity Conflict (LIC) group in collaboration with DRDL, Hyderabad.
- 2010 through 2012
Activities on NPMICAV projects Transfer of MUAV units to TASL and contract conclusion
First project with AU completed - MICAV takeoff from UGV, collaborative with Drone Aerospace, Bangalore. • MUAV demo at Kolar to NDMA • Contract signed with the Tatas(TASL) for manufacture and supply of UAV’s to government civil security and disaster management agencies
Participated in the MAV 08 international compe- tition at Agra, and the Indo US INDUS 2008 workshop •New smallest Brushless motor added to the Mighty Midget family 0.6g, 8g thrust •Initiated into NDRF consortium for activities under the NPMICAV Programme
Third generation Mighty Midget 1.5g BL sup- plied to prestigious DELFT university, Netherlands smallest in the world then, standard motor for the DELFLY II micro flapper • Development and export of the first micro EDF BL, weighing 3.1g and capable of 100,000rpm • Entered the first Indian MICAV competition held at Agra and won in three categories – Fixed Wing,- Flapping Wing and Special (propulsion) category
Mighty Midget second generation Goldline high performance BL motors introduced in developed mar- kets, UK dealer appointed – world standard for BL performance-thrust to weight ratio 30:1 established. Standard valid till date.
Initial batch of Mighty Midget motors sent to dealers in USA, Germany and France,streamlined production techniques after overwhelming response from customers abroad.
Seriously looked at the possibility of the de-velopment of the first commercial micro brushless three phase out runner type synchronous electric mo- tors running on Lithium Polymer battery technology, for RC model aircraft applications with ratio of static thrust/weight of aircraft > 1, all up weight under 50gm
