A Drogue Chute (short for Drogue Parachute) is a parachute designed not for the usual purpose, but to slow down a vehicle, such as a jet airplane landing on a runway. It is modeled after Drogues, similar devices used in the water by ships for stability during storms.
In Solar System exploration, drogue chutes may be used in approaching other solar system planets or Moons if they have sufficient Atmosphere, avoiding the fuel mass that would be necessary to carry out the same deceleration with a rocket burn. Such a drogue chute might be a Supersonic Parachute, capable of slowing the vehicle from a speed faster than sound in the atmosphere. Faster-than-sound stability adds complication to the design.
