The Automaton

 

 

 

DLE-JW02-A2

        The Automaton

   

Wingspan                      : 1520 mm ( 59.84 inch )

Length                           : 788 mm ( 31.02 inch )

Height                            : 308 mm ( 12.12 inch )

Estimated A.U.W            : 1856 g – 2200 g ( 65.46 oz – 77.60 oz )

 

The automaton is designed to serve as a suitable platform for FPV/UAV mission. Besides the amount of payload carrying capability, flight efficiency also becomes the main priority in the design consideration. The FPV gears which consist of CCD camera, AV transmitter, OSD, etc; could be incorporated with the autopilot modules in order to provide aerial view through a ground control station in an autonomous flight mission. To achieve complete information, airspeed sensor, GPS, OSD telemetry and data link Tx/Rx should be included in the autopilot modules.

The UAV Automaton, DLE-JW02-A2, development phase 01

The Automaton is presented by Angel Gendut Productions.

 

UAV / FPV Platform : DLE-JW02-A2

Development Phase 01 : Airframe performance test

 

Wing Span             : 1.5 m

Control Surface     : 2 Flaps and 2 Ailevators

Tested A.U.W         : 1.9 kg

 

Tested Drive system :

  • Brushless motor : Turnigy G10, 810kv, 375W
  • Speed Controller : Turnigy Trust 55A SBEC with internal switch-mode BEC 5.5V/3A
  • Electric Nylon Propeller : Revox 12x6E
  • Servos : 4 x Emax ES08MD Digital, Metal Gear servo
  • Li-Po Batt : Turnigy nano-tech 4S-2200mAh (35C-70C)  OR  Zippy Compact 4S-2200mAh (35C)
  • 409 grams of solid lead (As weight simulation)

 

Radio Tx/Rx system:

  • Tx : Futaba T8FG Super, 2.4 GHz transmitter
  • Rx : Futaba R6028SB, 8ch 2.4 GHz receiver

 

Design review :

  • 409 grams of solid lead is attached to the cockpit to simulate the payload of FPV and autopilot gears; resulting in 1.9kg of A.U.W.
  • Airbrake mixing is implemented to preset the flaps and ailevators positions for hand-launch take-off and landing.
  • The Automaton is easy for hand-launch take-off, easy for maneuvers, has sufficient lift production for carrying large amount of payload, has lots of thrust for both high and low speed flight.
  • Flaps are proved to be effective during the emergency landing procedure; it is also used during a low speed/cruise flight.
  • Implement average throttle range of 30% – 60% for efficient flight to increase flight duration.
  • 3S Li-Po batt is yet to be tested to further improve the flight duration.
  • FPV gears are to be mounted in the next development phase; followed by Autopilot modules with data link.

Stalling the Black Diamond


 

Flight test of the Black Diamond with lesser A.U.W and a little tail heavy setup.

 

UAV / FPV Platform : DLE-XT-47

 

Tested Drive system :

  • Emax BL 2220-07, 1200kv
  • Turnigy Plush ESC 40A
  • Emax UBEC 3A
  • Revox 10x7E Prop
  • Emax ES08MD Digital, Metal Gear servo
  • Turnigy Nano Tech 3S-2200mAh (35C-45C)
  • a roll of tapes is attached to the nose to act as a counter weight to readjust the C.O.G backwards toward tail ( a little tail heavy )

 

Tx/Rx system:

  • Futaba T8FG Super, 2.4 GHz transmitter
  • Futaba R6028SB, 8ch 2.4 GHz receiver

 

Design review :

  • The Airbrake mixing is applied too much upwards angle for the ailerons and elevons; causing it to pitch up at high angle, then stall.
  • The model feels underpowered for quick maneuvers and vertical climb.
  • Lesser A.U.W makes 65 – 75% throttle for effective flight.
  • It is recommended to implement the previous setup using Turnigy Park 480, 1320kv with 10 x 7E or 9 x 6E Prop.

 


New drive system setup on the Black Diamond

 

Flight test of the Black Diamond using a new motor.

 

UAV / FPV Platform : DLE-XT-47

 

Tested Drive system :

  • Emax BL 2220-07, 1200kv
  • Turnigy Plush ESC 40A
  • Emax UBEC 3A
  • Revox 10x7E Prop
  • Emax ES08MD Digital, Metal Gear servo
  • Turnigy Nano Tech 3S-2200mAh (35C-45C) (Either one is connected)
  • Turnigy 3S-2200mAh (35C-45C) (Either one is connected)

 

Tx/Rx system:

  • Futaba T8FG Super, 2.4 GHz transmitter
  • Futaba R6028SB, 8ch 2.4 GHz receiver

 

Design review :

  • The model feels underpowered for quick maneuvers and vertical climb.
  • 80% – 90% throttle for effective flight; caused high heat production and inefficient flight.
  • It is recommended to implement the previous setup using Turnigy Park 480, 1320kv with 10 x 7E or 9 x 6E Prop.
  • Airbrake mixing is implemented to alter the ailevators and ailerons position for take-off (side hand-launch).
  • The second battery acts as a weight to simulate FPV gears’ weight.
  • Proper D/R, Expo, travel limit and ailevators ratio mixing setting for servos is required for maximum performance.
