The Kaman K-MAX American Helicopter
The K-MAX series would be the latest inside a lengthy type of Kaman synchropters, the favourite of the HH-43 Huskie. The very first turbine-powered helicopter seemed to be a Kaman synchropter.
The Kaman K-MAX American Helicopter
The K-1200 K-MAX “aerial truck” may be the world’s first helicopter particularly designed, examined, and licensed for repetitive exterior lift procedures and vertical reference flight (Kaman received IFR Certification in 1999), an essential feature for exterior load work. Other rotorcraft employed for these jobs are modified from general-purpose helis, or individuals meant to mainly carry people or internal cargo. The aircraft’s narrow, wedge-formed profile and protruding side home windows provides the pilot a great look at the burden searching each side from the aircraft.
The transmission includes a reduction ratio of 24 in three stages, and is made for infinite existence. The rotor rotor blades are made having a wooden spar and abs plastic trailing edge sections. Wood was selected because of its damage tolerance, fatigue resistance and also to make the most of area experience and qualification data accumulated from the similar spar around the HH-43 helicopter, designed for the U.S. Air Pressure within the ’50s and ’60s.
The K-MAX depends on the 2 primary benefits of synchropters over conventional helis. The very first could well be the best associated with a rotor-lift technology another may be the synchropter’s natural inclination to hover. This increases stability, specifically for precision operate in placing suspended loads. Simultaneously, the synchropter is much more attentive to pilot control inputs, which makes it easy to easily swing a lot thus to scatter seed, chemicals, or water on the bigger area.
A K-MAX has been utilized for demolition work by getting a destroying ball as sling load.
An unmanned remote-control version, the K-MAX Unmanned Multi-Mission Helicopter, is planned for hazardous missions. It may be utilized in combat to provide supplies towards the battleground, in addition to civilian situations including chemical, biological, or radiological hazards. A protype of the was proven in 2008 for potential military heavy-lift resupply use, and again this year. In December 2011 an unmanned K-Max was considered to be at the office in Afghanistan.
In December 2010 NAVAIR granted a $46 million contract to Kaman for 2 aircraft, as well as in 2011 they completed a 5-day Quick Reaction Assessment.
38 K-1200 K-MAX helis happen to be built. By May 2008, 13 of those weren’t airworthy or happen to be wiped off in accidents.

K-MAX Unmanned Helicopter
Lockheed Martin Corporation and Kaman Aerospace Corporation have effectively changed Kaman’s proven K-MAX® energy lift helicopter into an unmanned aircraft system (UAS) able to autonomous or rc cargo delivery. Its mission: battleground cargo resupply for that U.S. military.
The K-MAX UAS is really a life changing technology for a quick-moving battleground which will enable Marine corps to provide supplies either day or evening to specific locations without chance of losing existence along the way. The aircraft can fly at greater altitudes having a bigger payload than every other rotary wing UAS. Using its four hook slide carousel, the K-MAX UAS may also deliver more cargo to more locations in a single flight
They has flown the K-MAX UAS nearly 400 hrs in autonomous mode since joining forces in 2007. The rugged system can lift and deliver a complete 6,000 pounds of cargo at ocean level and most 4,000 pounds at 15,000 foot density altitude.
The K-MAX is constantly on the exceed anticipation being an unmanned platform. The aircraft has met all unmanned key events up to now and is constantly on the stand out available logging and firefighting industries. The aircraft will stay optionally piloted for easy National Airspace Procedures, periodic manned mission versatility, ferry plane tickets, rapid integration of recent mission equipment, and permit rapid return-to-service activities.
The manned version from the K-MAX can be used for repetitive lift procedures by commercial operators for that construction and logging industries. Up to now, the fleet has gathered a lot more than 255,000 flight hrs since 1994.
Application and Mission
The K-MAX® is a hard-working helicopter that was designed to perform under extreme conditions and circumstances, with less maintenance. It maintains its capabilities in hot temperatures and at high altitudes, delivering a measurable performance advantage for operators working in harsh conditions. The K-MAX® is well suited to a variety of missions and applications, including:
• Construction in wildlife protected areas
• Firefighting, with precise water drops: FIRE-MAX application
• Emergency response
• Disaster relief, i.e. delivering supplies, removing obstacles
• Timber harvesting
• Oil and gas exploration
• High-rise firefighting
• Data relay station placement
• Wind energy construction support
• Emergency rescue
• Mobilization and logistics
• Construction, such as ski-lifts, oil rigs, pipelines, and concrete work
• Power line construction and repair
The K-MAX® consistently delivers superior, reliable performance. Mission after mission. Day after day. Year after year.
The K-MAX® can lift more than it weighs – 6,000 lbs.
The K-MAX® burns an average of 85 gallons of fuel per hour during lift operations, the most efficient lift-to-fuel ratio of any helicopter in its class.
