Tethered flight test

Tethered rocket test
Tethered VTOL test

A tethered flight test is a type of flight testing where a machine is connected by a tether to the ground. Tethered testing may be used when motion through the atmosphere is not required to sustain flight, such as for airship;[1] VTOL, rotary wing or tiltwing aircraft (tethered hovering);[2] or for tests of certain rockets, such as vertical takeoff, vertical landing (VTVL). Fixed wing scale models can be tested on a tether in a wind tunnel, simulating motion through the atmosphere.[3]
