This IMHO is ISRO's first flight prototype of hypersonic engine in actual flight, atop a modified Rohini rocket stage. The nose will pop out at cruising altitude (~30-40 km) and the wedge shaped inlet to hypersonic engine will show up.
ISRO is rumored to have tested early elements of hypersonic engine atop a SLV booster, many years ago.
