We have designed the DeltaQuad to be among the safest UAVs in the world. The DeltaQuad Pro extends the safety features even further with DSPS.
Vertical Technologies has designed a system called QuadChute which is blend of the words quadcopter and parachute. The QuadChute subsystem monitors the vehicle during forward flight. Should it prove incapable of holding its altitude or desired attitude it will revert back to quadcopter mode and return safely to its takeoff point. If it the battery capacity does not allow the vehicle to return it will land on a designated failsafe location* or it will perform a slow landing as close to its takeoff point as it can get. At any time the operator can intervene and guide the vehicle to a safe location by a simple click on the map. By employing this system the DeltaQuad takes full advantage of its redundant flight system and effectively makes it impossible for the vehicle to crash in forward flight mode.
The DeltaQuad ground control station will verify the altitude of every mission waypoint and will warn you if the selected flight altitude drops below ground level.
The Pro series extends the waypoint elevation verification by verifying the entire path of the vehicle and warn if at any position it will be flying at an unsafe altitude.
DSPS uses its internet connectivity to monitor surrounding air traffic using the international transponder standard ADS-B. When an aerial vehicle that publishes its location through ADS-B comes within unsafe distance to the DeltaQuad it will take preventive action. Pre-flight DSPS will not allow the DeltaQuad to take off, during flight DSPS will take warn the operator and take evasive action if needed.
DSPS uses its internet connectivity to check if the current and forecasted weather conditions at it's takeoff and landing position fall within the maximum rated conditions. Depending on its configuration it can either issue a warning or ground the vehicle.
Before starting a mission DSPS will check the feasibility of the mission given the battery capacity and current weather conditions. It will prevent an operator from executing a mission that it can not complete. During flight it will continuously monitor the feasibility and can make an intelligent decision if the conditions change making it unfeasible to complete its mission. if it becomes unfeasible to complete the mission given the current conditions but it is feasible to return to its takeoff point it will do so. If it is not feasible to return to its takeoff point but t is feasible to head directly to its destination it will do that. If neither of these are feasible it will land on a designated failsafe location* or land as close to its takeoff or destination point as it can get.
Comparable to a cars 'check engine' light DSPS continuously monitors the systems sensors and behavior. When a value exceeds acceptable limits the system will warn the operator and in some cases ground the vehicle or abort the takeoff. ASM monitors the following;
In the event that the GPS receiver fails or the signal is lost the DeltaQuad will do the following;
The DeltaQuads standard behavior when losing contact with the ground station is to return to its takeoff position and land. The DeltaQuad can also be configured to proceed on its mission even when losing contact with the ground station. This behavior is only recommended for the DeltaQuad Pro and might not be legal in certain countries.
