With a max gross weight of nearly 29,000 pounds, the Mil Mi-17 is no small helicopter. It is a workhorse that has gained a considerable following in most parts of the world. More than 10,000 Mi-17s and Mi-8s (from which it was derived) have been delivered for both military and civilian roles since the 1960s, including more than 2,400 for export. Some 200 are operating in Central America and the northern countries of South America.

That new aircraft are often derived from earlier models is no surprise, but hybrids of two separate bloodlines are rare. The Eurocopter EC 145 medium twin, derived from the venerable BK 117 and the much newer EC 135, is one such hybrid. But unlike many mergers, particularly in the corporate world, this one actually works.

In the face of what market forecasters predict will be nearly another full decade of flat civil helicopter sales, manufacturers have been loath to risk precious capital to develop models whose market reception would likely be less than enthusiastic.

Providing proof that persistence pays off, Sikorsky Aircraft received in the week before Christmas a most welcome present: type certification of its S-92 medium-twin transport helicopter (initially limited to VFR operations).

Taking its place on Bell Helicopter’s Arlington, Texas, tiltrotor test stands for the first time last month, the long-awaited first of a planned four Bell/ Agusta 609 convertiplane prototypes began its engine runups in December. First flight is loosely scheduled for the first quarter of this year. The six- to 10-passenger aircraft will undergo a planned 40 to 50 hr of static testing before flight.

Carson Helicopters of Perkasie, Pa., has been granted FAA certification for new main rotor blades for the Sikorsky S-61. The design incorporates two airfoils and 12 degrees of twist, giving the venerable Sikorsky workhorse 2,000 pounds more lift in a hover and adding 15 knots to the cruise speed compared with the standard metal blades at the same power settings. Carson has signed a contract with NASA for exclusive use of the airfoils.

I have to admit that the Robinson revolution passed me by. I graduated from flight school in the U.S. Army in 1978, the year before the first R22 was certified. After seven years in the army, my civilian career path led directly to multi-engine turbine helicopters, a world apart from single-engine pistons.
