Multifunctional.-

As the Bell/Boeing team that produced the MV-22 eyes its next possible U.S. sale to the Navy for a C-2 replacement, the industry team is hoping to drive home the idea that the tiltrotor is multifunctional. The team is confident the tiltrotor can safely refuel F/A-18s midair after conducting the first proximity test between the two last week.

A Hornet flew within 30 ft. of the MV-22’s drogue chute in a lateral offset position during an August 29 flight trail. This was the fourth in a series of tests paid for by Bell/Boeing as the team examines alternative missions for the V-22.

The U.S. Marine Corps is the primary customer for the aircraft with a program of 360 aircraft, with the U.S. Air Force also buying 50 of the aircraft to replace its retired MH-53s. The team opted to sponsor the trials in hopes of capturing interest from one of its existing customers and to also whet the appetite of the Navy as it looks at alternatives to replace the aging C-2 Greyhound Carrier Onboard Delivery (COD) platform with 48 or more aircraft. The team is clearly trying to send the message that the Osprey will be a multi-mission option.

Whether that influences the shape of the competition remains to be proven. But, the cost of the Osprey has not dipped below $60 million as once hoped by the team and customers alike. The target price is $70 million in the next multiyear buy of Ospreys, in part owing to reduced production rate funded by the Pentagon. The team has a bevy of international prospects, but each is for only a handful of aircraft. So, the biggest tender yet to get remains capturing the interest of the U.S. Navy.

The industry team is hoping the U.S. Navy or Marine Corps will provide funding for additional testing to include contact between the refueler and receiver and, eventually, passage of fuel between the two. The team had looked at the concept of using the V-22 as an aerial refueler for years but the effort gained steam at the beginning of the year. Prior to last week’s flight, the company validated the ability to extend and retract the refueling hose and drogue, a Cobham model also used by the Marine Corps’ KC-130 fleet. Also prior to the proximity flight, the team collected data on the behavior of the Hornet in the MV-22’s wake and pilots didn’t report any significant wake turbulence, noting the feedback validated expectations based on prior modeling and earlier input from the pilot of a Cessna surrogate used to study the MV-22’s wake. During the Aug. 29 test, the two aircraft were traveling at 210 kt. The high-speed version of the hose/drogue refueling system is designed to be deployed at 185 kt. and function at up to 250 kt.
