NAL/ADE Pushpak
A joint DRDO-NAL micro air vehicle technology demonstrator.
The NAL/ADE Pushpak is an unmanned Micro Air Vehicle (MAV) technology demonstrator developed jointly by the Aeronautical Development Establishment (ADE) of DRDO and the National Aerospace Laboratories (NAL) of CSIRI. It is one of the airframe designs being pursued under the National Program on Micro Air Vehicles (NP-MICAV). The Pushpak is notable for its dihedral delta platform shape, pusher configuration, and nose-mounted payload, which contribute to cleaner aerodynamics and low wing loading.

Lore & Background
The Pushpak was developed as part of the National Program on Micro Air Vehicles (NP-MICAV), a collaborative effort between the Aeronautical Development Establishment (ADE) of DRDO and the National Aerospace Laboratories (NAL) of CSIRI. Its airframe is constructed from GF/Kevlar and features a dihedral delta platform shape, with the propeller mounted behind the motor in a pusher configuration. This design emphasizes cleaner aerodynamics, nose-mounted payload, high endurance, and low wing loading.
The vehicle is powered by an electric motor and carries a small camera capable of recording activities on the ground. It has an operational range of 2 km and can capture video from an altitude of 100 m. The Pushpak is remotely radio-controlled and is also equipped with an autopilot. A high-tech GPS positioning system allows it to track its trajectory and destination using the shortest path and most secure trajectories. As of 2012, prototypes were under flight trials.
Reader's Guide
The NAL/ADE Pushpak represents a focused effort within India's National Program on Micro Air Vehicles to develop a compact, fixed-wing MAV technology demonstrator. Its significance lies in its role as a testbed for key design features such as the dihedral delta platform, pusher configuration, and nose-mounted payload, which together aim to achieve cleaner aerodynamics and low wing loading. The integration of an autopilot and GPS positioning system for trajectory tracking underscores the program's interest in autonomous navigation capabilities. With a half-hour endurance and 2 km range, the Pushpak is intended for short-range reconnaissance tasks, using a small camera to record ground activities from 100 m altitude. The joint development by ADE and NAL highlights institutional collaboration in Indian defense and aerospace research. As of 2012, the prototypes were undergoing flight trials, indicating that the Pushpak was still in an experimental phase. Its legacy is as a stepping stone within the NP-MICAV framework, contributing to the evolution of micro air vehicle technologies in India.

Frequently Asked Questions
What is the NAL/ADE Pushpak?
The Pushpak is an unmanned Micro Air Vehicle (MAV) built as a technology demonstrator under India's National Program on Micro Air Vehicles (NP-MICAV). It is a fixed-wing, pusher-propeller craft with a dihedral delta airframe and a nose-mounted payload bay.
Who developed the NAL/ADE Pushpak?
It was created through a joint effort between the Aeronautical Development Establishment (ADE) under DRDO and the National Aerospace Laboratories (NAL) under CSIRI. The two agencies collaborated on the airframe design and systems integration for the NP-MICAV program.
What makes the Pushpak's airframe design distinctive?
Its dihedral delta platform combined with a pusher propeller layout and nose-mounted payload gives it cleaner aerodynamics and notably low wing loading. The structure is built from glass-fibre/Kevlar composites, keeping the airframe lightweight for micro-scale flight.
What are the Pushpak's flight endurance and range?
The demonstrator is rated for roughly thirty minutes of continuous flight and an operational range of about two kilometres. These figures reflect its role as a short-duration technology demonstrator rather than a long-endurance operational platform.
Why is the NAL/ADE Pushpak important to India's UAV development?
It serves as a proof-of-concept for micro-scale fixed-wing UAVs, validating airframe and propulsion concepts that can inform future small reconnaissance or surveillance vehicles. As part of the NP-MICAV program, it helps India build indigenous capability in the micro-air-vehicle segment.
