The Defense Research and Development Organization of India is developing the Hypersonic Technology Demonstrator Vehicle (HSTDV) to demonstrate hypersonic flight at Mach 6.5. The HSTDV will use a solid rocket booster and scramjet engine to attain autonomous flight up to 20 seconds. Initial flight testing will validate the vehicle's aerodynamics and test the performance of its thermal protection systems and scramjet engine. Engineers aim to begin testing a full-scale prototype in the near future.

1. INDIA’S HYPERSONIC TECHNOLOGY DEMONSTRATOR VEHICLE (HSTDV)
PROJECT – A TECHNOLOGICAL MARVEL!!

3. Introduction
 The HSTDV is an
unmanned scramjet demonstration
aircraft for hypersonic flight (Mach 6.5).
 The HSTDV program is run by the
DRDO.

5. Details
 The Defense Research and Development Laboratory’s
Hypersonic Technology Demonstrator Vehicle (HSTDV) is
intended to attain autonomous scramjet flight for 20 sec., using a
solid rocket launch booster.
 The research will also inform India’s interest in reusable launch
vehicles. The eventual target is to reach Mach 6.5 at an altitude
of 32.5 km. (20 mi.).
 Initial flight testing is aimed at validating the aerodynamics of the
air vehicle, as well as its thermal properties and scramjet engine
performance.
 S. Panneerselvam, the DRDL’s project director, says engineers
aim to begin flight testing a full-scale air-breathing model
powered by a 1,300-lb.-thrust scramjet engine in near future.

7. Development
 The design for airframe attachment with the engine was
completed in the year 2004.
 Israel has provided some assistance on the HSTDV program,
including wind tunnel testing, as has Cranfield University of
the U.K.
 Due to technology denial of material for the scramjet engine,
a new program was initiated and the materials were
developed in-house.
 This led to self sufficiency in the area and the scramjet
engine was ground tested successfully for 20s instead of the
initial 3s.

9. Progress
 In November 2010, DRDO officials told press that they were
in the process of opening four state-of-the-art facilities inside
as well as in the vicinity of Hyderabad at a cost of more
than 10 billion (US$162 million) over the next five years.
Reportedly, they will invest 3 to 4 billion (US$66 to 88 million)
for setting up a much-needed hypersonic wind tunnel at
Hyderabad’s Missile Complex.
 As of December 2011, the scientists had proved technologies
for aerodynamics, aero-thermodynamics, engine and hot
structures through design and ground testing.
