And, they want it in two years.....
1. Maximum Airspeed - 145 knots
2. Endurance - 4 hour with 500 kg payload with full fuel
3. Ceiling - 20000 feet
4. Autonomy - fully autonomous takeoff, waypoint navigation and landing
5. Datalink range - 200 km (just electronics)
6. Operating Temperature - -40 to +71 C degree
7. Wind - Up to 30 knot wind (That's hard for even a manned helicopter)
Question;
How do I build something that can hold up to an ambient outside temperature of 71C? Can it be done? Anyone with any experience of a C20 turbine operating in that condition?
I estimated vehicle empty weight at; 700kg (or less)
I calculate the fuel load at 380 continuous shaft HP: 530kg
Vehicle max gross weight: 1730kg
All on the edge, but within the numbers...... But I would have to move to East Europe.
