The Aeronautical Development Establishment (ADE), a premier lab of DRDO, has issued an Expression of Interest (EoI) inviting reputed Indian and global industry partners for the procurement of suitable power plant for HALE unmanned aerial vehicles (UAVs) currently under development.
The EoI seeks firms with proven expertise in the aerospace and defence sector, especially in aircraft power plants, propulsion systems, and integration of turboprop engines. The aim is to shortlist partners for a forthcoming Request for Proposal (RFP) to procure and integrate suitable UAV powerplants.
Technical Scope
ADE has specified that UAV turboprop engines should deliver:
• 900–1500 SHP @ ISA
• Dry weight below 700 lbs
• Specific fuel consumption <0.555 lb/hp-hr
• Service ceiling above 45,000 ft
• Time Between Overhaul (TBO) exceeding 3000 hours
Additionally, the partner must provide complete engine accessories, constant-speed pusher propellers, and fuel system components including filters, valves, sensors, and auxiliary equipment.
Phased Collaboration
The scope of work is spread across four phases:
1. Design Phase – Support in airframe integration, selection of accessories, and design documentation.
2. Development Phase – Technical support for nacelle design, exhaust manifolds, mounting frames, and delivery of engines and propellers.
3. Evaluation & Testing – Assistance in test-bed trials and propulsion system validation.
4. Integration & Post Delivery Support – Installation on UAV platforms, long-term maintenance, training, and lifecycle support for up to 10 years.
Stringent Partner Criteria
Interested industry players will be evaluated on financial strength, technical expertise, manufacturing capability, and management compliance. Key requirements include:
• Annual turnover of at least ₹75 crore and net worth of the same.
• Minimum 5 years’ experience in manufacturing/integration of aerospace systems.
• Proven capability in CATIA-based design, OEM approvals, and certification from CEMILAC/DGQA.
• Compliance with ILDC requirements for handling classified projects.
• Commitment to provide lifecycle support including MRO, spares, and training.
Strategic Significance
By seeking strong private and global partners, ADE aims to strengthen indigenous UAV development under the ‘Atmanirbhar Bharat’ initiative. The program is expected to not only boost self-reliance in defence propulsion technologies but also open avenues for exports in the UAV sector.
