[[File:First flight test of DRDO ABHYAS HEAT on 13 May 2019.jpg|thumb|DRDO ABHYAS undergoing flight tests, 13 May 2019]]
'''DRDO Abhyas''' is a high-speed [[target drone|expendable aerial target]] (HEAT) being built by the [[Aeronautical Development Establishment]] (ADE) of the [[Defence Research and Development Organisation]] (DRDO) for the [[Indian Armed Forces]].<ref name=a>[http://newindianexpress.com/cities/bangalore/article1470228.ece DRDO developing high-speed target drone Abhyas]</ref>

==Design==
The fuselage for the Abhyas was designed by adopting the [[Lakshya PTA|DRDO Lakshya]] tow body (not the main fuselage).
The fuselage consists of five sections, namely the [[nose cone]], equipment bay, fuel tank bay, air intake bay and tail cone.
The material for the nose and tail cones are made up of composite material ([[Fibre-reinforced plastic|GFRP]]), whereas the material of the equipment bay, air intake bay and fuel tank are made up of an aluminum steel [[alloy]].
The wings and tail plane of the Abhyas have been derived from the Lakshya by downsizing them, however the wings of the Abhyas are positioned on the upper-side of the body whereas the Lakshya has under-body wings.
For propulsion it is fitted with a gas-turbine engine, having a thrust of 25 kg, with an endurance of 30–45 minutes.
Abhyas is [[GPS]]-enabled, has an on-board flight control computer and a miss-distance indicator. It is also designed for autonomous flight with the help of an [[autopilot]].

==Flight Profile==
The Abhyas is launched from a mobile launcher with the help of two 68 mm booster rockets (being manufactured at ordinance factories). At the end of its launch phase the burnout booster rockets are jettisoned. Thereafter, the main gas-turbine engine powers the vehicle during cruise phase.<ref name=a/><ref>{{Cite web |url=http://vijainder.sawfnews.com/Articles/70364.aspx |title=Archived copy |access-date=2013-02-19 |archive-url=https://archive.is/20130411183506/http://vijainder.sawfnews.com/Articles/70364.aspx |archive-date=2013-04-11 |url-status=dead }}</ref>
===Flight testing===
DRDO conducted successful flight test of ABHYAS- High-speed Expendable Aerial Target (HEAT) from ITR [[Balasore]] in [[Odisha]] on 22nd September 2020. Two demonstrator vehicles were successfully test flown. The vehicle can be used as a target for evaluation of various missile systems.<ref>{{cite web|title=DRDO conducts successful flight test of ABHYAS – Know all the features| url=https://www.timesnownews.com/india/article/drdo-conducts-successful-flight-test-of-abhyas-know-all-the-features/656444}}</ref>
<ref>{{cite web|url=https://indianexpress.com/article/india/drdo-conducts-second-successful-flight-test-of-missile-target-vehicle-abhyas-6607006/|title=DRDO conducts second successful flight-test of missile target vehicle Abhyas}}</ref>

==Transportation & storage==
The Abhyas drone has a dedicated box for its transportation and storage (2570 mm * 710 mm *415 mm) made of EPE (Expanded Polyethylene]) and with an XLPE ([[Cross-linked polyethylene]]) foam material inside. It is weather proof, drop and vibration proof and static load-tested.

==Usage==
Abhyas's [[radar cross-section]] (RCS) as well as its visual and [[infrared signature]]s can be augmented to simulate a variety of aircraft for air-defense weapon practices. It can also function as a jammer platform and decoy. The HEAT system is utilized to do away with the post-launch recovery mode, which is time-consuming and difficult in a scenario as the sea.

==Development==
As of January 2013, the proof of concept and pre-project trials were completed.
The first experimental launch (without the main engine) of the Abhyas was held at the [[Chitradurga Aeronautical Test Range]] on 23 June 2012. The gas turbine engine has been identified and integrated on the Abhyas airframe and its test run with the aircraft fuel system and s-airtake has been completed.
The project was sanctioned with an initial DRDO funding of [[Indian rupee|Rs]] 150 million and the ADE carry out 15 technology demonstrators (TDs) over the next two years.
After the acceptance of the prototypes or TDs by the [[Indian Armed Forces]], serial production will start.
The Indian Defense Services have also revealed a combined global tender projecting the requirement of 225 HEAT drones.
