A Vertical Takeoff and Landing (VTOL) experimental plane being developed under a DARPA program aims to achieve a top sustained flight speed of 300 kt-400 kt.
Understanding VTOL Speeds
The speed of a VTOL aircraft can vary significantly depending on its design, size, and intended use. Unlike traditional fixed-wing aircraft or helicopters, VTOLs are designed to lift off and land vertically, but often transition to horizontal flight for cruising. This transition capability allows some advanced VTOL designs to potentially achieve higher speeds than conventional helicopters.
Speed Target for a DARPA Experimental Plane
According to the DARPA program information for the "Vertical Takeoff and Landing Experimental Plane," a key performance goal is speed. The program specifies the target:
- Speed: Achieve a top sustained flight speed of 300 kt-400 kt.
This speed represents the maximum speed the experimental aircraft is designed to maintain during horizontal flight after transitioning from vertical takeoff.
What are Knots (kt)?
Knots are a unit of speed commonly used in aviation and maritime contexts.
- 1 knot (kt) is approximately equal to:
- 1.15 miles per hour (mph)
- 1.852 kilometers per hour (km/h)
Therefore, the target speed range of 300-400 knots translates to:
- 300 kt: Approximately 345 mph or 556 km/h
- 400 kt: Approximately 460 mph or 741 km/h
This range represents a relatively high speed for an aircraft capable of vertical takeoff and landing, comparable to the speed of some turboprop aircraft.
In summary: While VTOL speeds vary, a specific DARPA experimental program targets a top sustained flight speed between 300 and 400 knots (approx. 345-460 mph or 556-741 km/h).
