1:11 Scale GHATAK WT Model At HAL

Program Sanction 

A Draft PSQR compliance document sent to Air Hq. PSQR is finalized by Air Hq on 10th June, 2016. A lead-in project for “Design of GHATAK and Development of Critical Advanced Technologies for GHATAK and AMCA” is sanctioned for Rs.231.00 crores on 13th May 2016.

Major technologies to be developed under this lead-in project are broadly classified under five technological categories:

(a) Model Based Systems Engineering (MBSE)
(b) Autonomous flight control technologies
(c) Aerodynamics and Propulsion technologies
(d) Stealth computations, measurements, structures & materials
(e) Technologies for GHATAK systems

Focused advanced design tools for Multi-Disciplinary Optimization (MDO) using a HPC computing infrastructure will be developed for flying wing configuration improvement studies. Levels of flight autonomy will be increased through testing of ATOL and FADS on LCA and scaled autonomous flight demonstration of GHATAK. Through 1/6th scaled flight model of GHATAK, technologies like control law for flying wing, fluidic thrust vectoring and stealth materials will be tested and evaluated in a cost effective way.

TRLs of critical advanced technologies like conformal antenna, SAR, EO/IR, FADS shall be improved and adapted for GHATAK. Full scale GHATAK RCS model will be tested at ORANGE facility to evaluate RCS hot spots and to enable RCS reduction. Weapon release studies and deployment mechanism would be studied using high fidelity unsteady CFD modeling of URANS. Effective ejector based cooling mechanism for embedded high aspect ratio nozzle will be combined with ECS cooling requirements along with compact heat exchangers.


Several Advanced Technology proposals for GHATAK and AMCA from DRDO Labs is received and reviewed. First Review meeting for 16 Advanced Technology proposals received from DRDO is completed on 12th and 13th of July, 2016. Based on this review, suggestion for modifications of these proposals has been made. Preliminary cost has been estimated by an ADA internal cost committee and a preliminary draft CCS proposal report is prepared based on this cost estimates for possible submission later.

Work on latest GHATAK configuration 2.3

Status of Power Plant

GTRE had submitted a draft CCS proposal for a Dry engine for the GHATAK along with “In-principle” approval of GHATAK Program to ADA. After clearance from MoD and MoF, draft was submitted by GTRE to the PMO. A High Level Committee was set up under Chairmanship of Dr. R Chidambaram (PSA to GoI), with Dr. V K Saraswat (Member, Niti Aayog) and Dr. K Radhakrishnan (Former Chairman ISRO) as members. The committee has submitted its report to the PMO.

Confidence In Development of GHATAK UCAV by ADA

The committee endorsed the confidence in the GHATAK aircraft development by ADA based on the design capability assimilated in ADA in developing the Light Combat Aircraft (LCA) being

utilized for configuration finalization for “GHATAK” aircraft. 12.4 Recommendations of the committee. The UCAV aircraft and engine technology is highly classified and is unlikely that any country would share this technology with India. Hence it is inescapable requirement to develop an Indian UCAV and its engine considering the future combat warfare scenario. The development of an unmanned combat aircraft is a “national imperative” toward self reliance in aerospace technologies.

The committee strongly recommended the sanction of the project at the earliest to be at par with other developed countries.

Work Share Allocations For The Program

The committee also submitted the work share allocation of for executing the GHATAK aircraft program with program office and prime responsibility with ADA, and indicated responsibility with ADA, and indicated responsibility to DRDO, HAL & other labs.

Way Forward

At the moment no GHATAK aircraft program has been sanctioned to ADA and only funds for developing advanced Technologies have been sanctioned. Using these funds some of the critical technologies will be developed within the country through sponsored projects.
