The thrust-to-weight ratio is calculated by dividing the thrust (in SI units – in newtons) by the weight (in newtons) of the engine or vehicle.The weight (N) is calculated by multiplying the mass in kilograms (kg) by the acceleration due to gravity (m/s 2).
The new configuration reduces weight to 8 kg (18 lb), allowing for a 1 kg (2.2 lb) payload to be carried, such as a miniaturized electronic warfare package. In addition to being able to land vertically, the updated version adds a parachute at the rear of the airframe.
DRDO Abhyas test flight on 23 December 2021. As of January 2013, the proof of concept and pre-project trials were completed. The first experimental launch without the main turbojet engine of the Abhyas was held at the Chitradurga Aeronautical Test Range on 23 June 2012 to check the launch and configuration capability.
