T-Works built autonomous hybrid UAV covers 45km

Hyderabad City-based makers lab T-Works on Thursday said it has developed an indigenous vertical take-off and landing (VTOL) autonomous unmanned aerial vehicle (UAV) that can cover up to 45 km in 33 minutes. This UAV has completed over 30 test flights over the course of a week, passing various parameters such as maximum range, endurance, waypoint navigation, and return-to-launch capabilities, it said.

T-Works designed and fabricated the airframe and its components using software design tools, 3D printing, laser cutting, and CNC routing machines.

A winged aircraft consumes up to 75% less power than a conventional multi-rotor since the wings help produce the additional buoyant force, as a result of which it can carry much heavier payloads over much larger distances.

Sujai Karampuri, CEO T-Works, said “The best battery powered multi-rotors in the world are limited to a 40km range while the most common and affordable ones are limited to around 20-25km after which the battery must be recharged or replaced. For wider applications and to cover longer distances, say over 100km, with speed, we must break this range barrier. Here, fixed-wing VTOL UAVs are an efficient option.”
Apart from medical supplies delivery, the UAV can be used for surveying, inspection, defence applications, surveillance, and as a testbed for experimental payloads. The next version of this UAV will have a range of 100km with a payload capacity of 3.5kg.

This is problem with people like him. Chest thumping.

This state of art is already been developed for CAESAR.
Bhai do u mean the 2006 varient off CAESAR or the latest AESA one in testing???

Do u mean this isn't a much of engineering capability for the exaggerating chest thumping??
Have the Russians and Chinese have this capability??

The E-variant for Typhoon and Gripen too most probably.

Generally AESA is fixed mounted as there is no need to steer the beam manually in it. But mounting it on a gimbal or electro-mechanical aperture like LRDE would increase its scan area. But along with it, it would make it more complex and maintenance heavy and may be costly too.

Chinese have a fixed mount as far as I know. Russians have gone a step ahead. They have fixed the RADAR across the dome fuselage to increase the scan area. But it too means immense work on data fusion and increase in price tag.

Most Probably a Small Scale prototype of OTH Radar . This one can track various sea targets within 100m accuracy. Range depends , other parameters also depends on the Frequency using . If we using it as ground wave Radar it may get more than 400Km range , If we using it as Skywave radar then 1000 to more than 4000 Km can be achieved . But not sure about which system it is. Both Receiving and transmitting arrays are present in the prototype so I guess it is a OTH Radar Prototype

The Myth of Atmanirbhar Bharat in Defence Manufacturing

The private sector must play a greater role if India's quest for self-reliance is to be achieved soon.

‘Corporatisation’ was listed as one of the 167 transformational ideas to be implemented in the first 100 days after coming to power in the NDA’s manifesto for the 2019 general elections.

The delay in announcing the corporatising of 41 ordnance factories is understandable, given its antiquity and the powerful and entrenched unions that they have with 81,500 employees.

India’s military industry capability shows a sorry picture and the private sector is still not being treated as a partner in India’s quest for higher self-reliance.
The much-hyped indigenous Light Combat Aircraft (LCA) is powered by a GE 404 engine from the US, while the radar is sourced from ELTA, Israel. The Kaveri engine development by the Gas Turbine Research Establishment (GTRE) has been an unmitigated disaster. The Main Battle Tank (MBT), the showpiece indigenous tank, is powered by German MTU engines. Despite the significant hike in FDI, the inflow has only been $300 million from April to September 2020. This is largely due to the number of caveats for allowing 76% FDI.

The time to shed flab and inefficiency in defence PSUs and ordnance factories has come, rather than gloat over the corporatisation of the OFB.

ISROs Multi objetctracking radar can track 10 , 0.25M2 Targets at 1000Km

ISROs Mobile MOTR which can track 10, 0.25m2 targets simultenously at 240km away .

both are pretty good candiadtes for miltary anti stealth radar. may be we already have anti stealth radar derives from these two radars , and DRDO is developing multi static radars for detecting stealth targets , anti stealth radars in multi static radar configuration is pretty much effective against stealth aircrafts .
