    The Mazda Rx-8 has a Wankel engine. It is very hard to make those kind of engines and they have high oil consumption if the seals are not done right. So it is a significant achievement. The RX-8 is in fact the only current production car which has a Wankel engine. They are good for high speed but have low torque, which is not a consideration for UAVs. So this is quite impressive.

    i remeber seeing a programme in discovery channel on science& technology development in India. one IISc professor had developed a wankel engine and he used it to power a microloght which he flew himself? could this be derived from that? Anyhow its good work . keep up it up ADE et al….

    Wankel engines are particularly good for aero applications because of their small size, low weight, low vibration and high power. Kudos to the DRDO for making it in-house. But I can’t but help thinking it is a case of re-inventing the wheel. They could have spent the time, effort and money on developing the control and avionics rather than actually building an engine from scratch. Small Wankel engines are readily available at dirt cheap prices off the shelf in Europe. Axiro produce a karting engine http://www.woelfle-engineering.com/ and Parajet produce two modified versions of these for personal avaiation (paramotoring) http://www.parajet.com/index.php?id=28 . These units cost less than £3000 for a retail purchaser (and much much cheaper for wholesale purchasers), which is nothing compared to the cost of the electronics on-board the UAV. Small companies like these which operate on small margins would be over the moon if someone like the DRDO bought their designs. It would be like a pension fund for them, and it would have no impact on their core business.
    Why don’t we just buy the rights to the basic design and modify it for our needs. It would save us so much time. Nevertheless, hats off to our boys.

    Its a good move by DRDO .
    DRDO should step in to create deadlier Attack UAV’s with help from other Leaders . India should place more orders in home grown weapons .

    Chinese Wankel engines might take on a whole new significance.
