20 min) is to develop a 'perch-and-stare' design, which suggests a helicopter, a ducted fan or an entomopter
(insect-like winged device), innovative work in the rotary-wing field includes the US Naval Research Laboratory Samara, which employs two single-blade contra-rotating rotors that are stopped to form a fixed wing in forward flight.
They expect the final entomopter to cruise along about as fast as a person runs.
However, because Mars' gravity is only 37 percent of Earth's, the entomopter should still be able to carry a payload of up to 1.
To make the entomopter especially efficient, the researchers are planning other innovations.
Also, by being vented through strategically placed openings on the wings, those gases will steer the entomopter and squeeze more lift out of the flapping-wing design.
People will see the benefits [of aircraft], and then further-out technology like the entomopter will be the next generation," Colozza predicts.
The entomopters fly off and come back, and they guide the rover," says Colozza.
