DRDO successfully conducts flight test of HEAT Abhyas

-

On Thursday, the Defence Research and Development Organization (DRDO) successfully conducted a flight test of the Abhyas, an indigenously built high-speed expendable aerial target (HEAT) off the coast of Odisha, at the Integrated Test Range (ITR) in Chandipur.

During the flying test, a high subsonic speed trajectory was exhibited at a very low altitude with high endurance. During launch, two boosters supplied initial acceleration, and a small turbojet engine was utilised to maintain a high subsonic speed for a long time. During the flight, the Bengaluru-based industrial partner's indigenous data link was successfully flown and tested.

The system's performance during the course of the flight has been confirmed by data collected by a variety of range instruments.

This indigenous unmanned aerial target system was created by the Aeronautical Development Establishment (ADE), a Bengaluru-based DRDO laboratory, in collaboration with other DRDO laboratories to suit the requirements of the Indian Armed Forces for aerial targets. The aircraft is guided by a ground-based controller and a MEMS-based Inertial Navigation System developed in-house, as well as a Flight Control Computer, to follow a pre-determined path in completely autonomous mode.

The successful test, according to Defence Minister Rajnath Singh, demonstrates the collaboration between science and industry.

Earlier, the the Indian armed forces earlier fielded the reusable Lakshya and Lakshya-2 high‐speed aerial targets. The Abhyas will be a successor to these drones. The defence forces wanted a non re-usable systems so that they can post-launch recovery modes, which are time-consuming and difficult in a huge scenario like the sea. Abhyas is not designed to be recovered following a training mission. 

What is a high-speed expendable aerial target  (HEAT) system?

The high-speed expendable aerial aerial targets drones are designed to present a realistic threat for training fighter pilots in an air‐to‐air combat. This systems can also simulate a variety of missile threats. These target drones often resemble radio-controlled model aircraft.

What are the features of the Abhyas Ariel Target?

Abhyas High-speed Expendable Aerial Target is powered by a gas turbine engine to sustain a long endurance flight at subsonic speed. It is launched using a pair of underslung 68 mm rocket boosters before engaging

The drone has a MEMS-based Inertial Navigation System (INS) for navigation, as well as a Flight Control Computer (FCC) for guiding and control. A laptop-based Ground Control Station is used to check out the vehicle, which is programmed for fully autonomous flying (GCS).

Indigenous tank T-90 Bhishma rolls out

-
Image
The first batch of the indigenously built T-90 Bhishma tanks was on Monday (August 24) flagged off by Minister of State for Defence MM Pallam Raju at the rolling out ceremony held at the Heavy Vehicles Factory, Avadi, in Chennai. The T-90S tank incorporates many new technologies in terms of mobility, protection, fighting capabilities, safety and communication. The tank is equipped with 125mm smooth bore gun stabilised in Elevation and Azimuth, 12.7mm anti-craft machine gun and 7.62mm co-axial machine gun supported with high accuracy sighting systems and Automatic Loader ensuring high rate of fire. A significant feature of this tank is its capability to fire guided missile in addition to conventional ammunition using the same main gun barrel. The integrated fire control system consisting of the gunner’s sight, guided weapon system and ballistic computer facilitates accurate firing of conventional ammunitions as well as the guided missiles. The built in Explosive Reactive Arm...
