JALDOST Airboat Blog Image


Recently, the National Aerospace Laboratories (NAL) unveiled the JALDOST airboat.



  • It is an airboat that operates on water.
  • It is designed to remove excess aquatic weed and floating waste from water bodies.
  • It has a closed airtight pontoon type hull to make it inherently unsinkable.
  • According to NAL, it has a hybrid propulsion system, comprising air propulsion and paddle wheel propulsion.
  • How it works?
    • The ability to travel through weed makes JALDOST an ideal platform to collect them and bring them to the shore.
    • A steel mesh belt conveyor system fixed in the front collects the waste. The collected waste falls on the horizontal deck conveyor.
    • After reaching the shore, the collected waste is unloaded by a rear conveyor system to trucks or tractors.
  • NAL has developed two versions of the airboat — JALDOST Mark-1 and an upgraded version JALDOST Mark-2.

Q1) What are Hydrophytes?

Hydrophytes are plants that are specially adapted to grow and thrive in water environments. The term "hydrophyte" comes from the Greek words "hydro," meaning water, and "phyton," meaning plant. These plants have evolved unique characteristics to survive and flourish in various aquatic habitats, such as freshwater and marine environments.
