DRDO VTOL Logistics Drone: One of the biggest challenges of the Indian Army is to deliver timely logistics to soldiers deployed in elevated hillsides. In many areas of control line (LOC) and real control line (LAC) the soldiers are positioned at heights ranging from 12,000 feet to more than 18,000 feet. It has always been difficult and costly to deliver rations, medicines, ammunitions, communication equipments and necessary spare parts in these areas.
Taking into account the same challenge DRDO Launched a new indigenous project. According to the RFI on behalf of the DRDO, such a high-altitude VTOL logistics drone will be developed, which can fly without runway, get into difficult hills and reach forward posts with heavy payloads. The project aims to make logistics supplies more fast, secure and reliable inaccessible areas.
DRDO VTOL Logistics Drone: Why is the Supply Large Challenge in Higher Places?
Several military checkpoints located on the northern borders of India are in areas where road contact is limited. Supply routes are disrupted several times due to heavy snowfalls, landslide, avalanche, fast winds and excessive cold. Under such circumstances, the army has to be dependent on the armpits, human porters and helicopters.
Helicopter There are effective means, but their flight costs are higher. Flights are affected in bad weather and a limited number of helicopters are planted in a variety of military works. Also the flying operation in areas with height is technically difficult.
That’s why it’s now being stressed on devloping a system that can automatically transport the required material troops without a pilot. (DRDO VTOL Logistics Drone)
What is High-Altitude VTOL Logistics Drone?
This will be a special type of unmanaged aerial vehicle, which VTOL i.e. will be developed with vertical take-off and landing capacity. This means that no runway will be needed to fly or descend.
The drone will fly from the smallest and no runway terrain of only 5×5 m and descend. This capacity is considered extremely important in the hillsides as the availability of flat lands is very low.
The complete design of this system will be indigenous and the technologies developed in India will be used.
Capacity up to 200 kg
The payload capacity of the drone will be up to 200 kg according to the project. The drones can be delivered a large amount of ration, medical material, ammunition or other essential military equipment at once.
The total weight of the drone will be more than 700 kg. It will be able to fly for about 100 kilometres, including 50 kilometres of one-way mission.
Maximum speed is placed about 120 kilometres per hour. This can significantly reduce the time it takes to deliver the material to the squares located in the dumb areas. (DRDO VTOL Logistics Drone)
Operational capacity up to 25,000 feet
One of the most important features of this project High-Altitude has capacity. The drone is being designed for service sealing up to 25,000 feet.
It will take-off from areas with a height of up to 15,000 feet. At such height, the air density decreases, which affects the performance of the normal engine and rotor system.
Due to this, the project has been emphasized to develop the propelation system necessary for a particular high-altitude operation. (DRDO VTOL Logistics Drone)
Indigenous heavy-fuel engine will be the most important part
The operation of the drone will be from the engine heavy-fuel internal condition engine (IC engine). This engine will be able to run on military fuels like JP-8 and diesel.
Heavy-fuel engine is considered more safe and practical for military use as the military is already using such fuels extensively.
Maintaining the performance of the engine in low oxygen conditions in altitude areas is a huge technical challenge. So the engine will be designed specifically for high-altitude operations.
The FADEC technology will be from engine control
Full Authority Digital Engine Control i.e. FADEC technology will be used in this project.
FADEC is a digital system that automatically controls engine fuel flow, power output, and performance. This increases the efficiency of the engine and gives better performance in changing conditions.
Temperature, air and air pressure are constantly changing in elevated mountain areas. The FADEC technology in such environments helps to maintain stable performance to the engine. (DRDO VTOL Logistics Drone)
The mission will be complete without the pilot
Military-grade autonomous flight control system will be applied in the drone. This system will be able to automatically blow the drone according to the preset route.
The drone will be equipped with capabilities such as point navigation, identification of obstacles and emergency recovery. If there is a communication block due to any reason, it will securely complete the mission or return to the prescribed location. (DRDO VTOL Logistics Drone)
Navigation will be in Multi-Layer Security
It is extremely important to secure navigation systems in border areas. So this drone will be mounted GPS, GLONASS and sailor based multi-configuration GNSS system.
The internal navigation system will also be used with it. Even if the satellite signal is blocked, the drone will continue the flight by estimating its position.
The drone will also have anti-jamming and anti-spoofing technology so that its functionality does not affect in the event of an electronic war. (DRDO VTOL Logistics Drone)
Precise delivery within two meters
The accuracy of payload delivery as per project is laid within two meters CEP.
CEP (circular error probability) means that the material delivered by the drone will drop or descend from the set location to the average of only two meters. It is considered to be extremely important capacity for hilly areas and small squares.
This will make it easier to deliver ammunition, medical material and other essential tools to the right place.
Extremely tough weather will also make operation
The drone will be made workable at temperatures ranging from minus 40°C to plus 60°C. It will withstand winds from 50 to 60 kilometres per hour during flight. Operation will also be possible in the air of 25 to 30 kilometres per hour at the time of take-off and landing. The weather changes rapidly in bordering mountain areas. So all-veder capacity is the key part of this project. (DRDO VTOL Logistics Drone)
Special Attention to Secure Communications and Cyber Security
Encrypted Military Datalink will be used for safe data communication between drone and ground control station.
The system will include AES-256 level encryption technology. Also special measures will be taken to protect against cyber attacks, signal spoofing and electronic disruptions.
It will be ensured that the information associated with the mission does not reach any unauthorized person.
Ground control station will be monitored
Portable and rugged ground control station will be developed for the operation of the drone. This station will display the information of drone status, speed, height and payload in real-time. Monitoring and control of multiple drones from the same station will also be possible. The mission planning and flight management software will also be developed with it. (DRDO VTOL Logistics Drone)
Emphasis on self-sufficient defense technique
Not only drones under the project but also the engine, flight control system, navigation computer, datalink, mission software, power management system and other important sub-systems have been emphasized indigenously devloping.
Technical proposals have been sought from industry, research institutes and academic organizations for this. A detailed description of the use of development time, cost, human resources, infrastructure and indigenous content has also been sought.
Technical components have been sought from Industry, Research Institutes and Academic Organizations for this project. He has also been asked how long it will take to develop this drone system, what will be the estimated cost, how many manpowers will need, what kind of infrastructure will be needed and how indigenous content will be used in the system.
