ApplicationsThe K-MAX is well suited to a variety of applications.Emergency response, including:

Disaster relief, i.e. delivering suppliesFirefighting, with precise water dropsMobilization and logisticsSearch and rescue

Construction, such as oil rig and pipelinePower line construction and repairTimber harvesting

K-MAX for Emergency ResponseIn case of emergency, K-MAX is the helicopter to call. The K-MAX was designed to perform under the most extreme conditions and circumstances, and it does just that.

It will maintain its capabilities in hot temperatures and at high altitudes, delivering a measurable performance advantage for operators conducting rescues or dropping water on fires in mountainous areas.

Its heavy-lift capabilities make the K-MAX ideal for diverse disaster relief missions. Its ability to work long hours and perform repeated lift operations would make the K-MAX invaluable in delivering relief supplies to an area devastated by floods, for example. K-MAX might also be used to rapidly remove debris in an earthquake-ravaged region...or to rescue those trapped on top of a high rise building.

In a worst-case scenario, call on the hardest-working helicopter in the fleet — the high performance/low maintenance K-MAX.

Conceived and designed to perform repetitive external lifting – the K-MAX performs that mission better than any other helicopter in the world. The single-engine, single-seat K-MAX is a rugged workhorse, and no helicopter works harder or more efficiently.

Performance? The K-MAX can lift more than it weighs —

6,000 pounds. Efficiency? The K-MAX burns 82 gallons of fuel

per hour during lift operations, the most efficient lift-to-fuel

ratio of any helicopter in its class.

DesignTo understand what makes the K-MAX better, just look to the

original design.

A simple, straightforward design has resulted in fewer

aircraft systems, and has shortened the load path between the

engine and the rotor system, enhancing the airframe’s ability to

handle the stress loads generated between the rotor system and

the cargo hook assembly during repeated lifting. This simplic-

ity of design also enhances the safety and reliability of the

K-MAX. Specific aspects of the design that merit a closer look

are the K-MAX’s unique cargo hook/trolley system and the

concept of vertical reference flight.

Cargo Hook/TrolleyKaman designed and built the K-MAX around its cargo hook,

which operates on a unique and functional trolley system. The

trolley system allows the hook to move back and forth across

the belly of the aircraft, enhancing aircraft and load stability.

Vertical Reference DesignThe K-MAX was also designed around the concept of vertical

The K-MAX effectively marries new

A look inside a K-MAX shows the source of its ruggedness. Besides

using high-strength aerospace-grade aluminum, we use the metal

in sheets up to 0.125 inches thick.

Built to Liftuilt to Lift

K-MAX brochure 20150206 FLAT.indd 2-3

The curved track in which

the cargo hook rides is

just part of the massive

structure that serves as

the centerpiece of the

K-MAX design. This heavily

reinforced structure delivers

reliable lifting day after day,

year after year.

The pilot sits literally above

the side windows, with all

necessary switches in the

cyclic and collective grips.

This view, in particular, shows the features that make K-MAX

so well suited to lifting and placing loads — a narrow, tapered

fuselage with bubble windows for unequalled pilot visibility

and the massive structure and unique “trolley” for slinging

6,000-pound loads.

Vertical Reference DesignThe K-MAX was also designed around the concept of vertical

reference flight, and the result is distinct advantages for pilots.

For example, the aircraft’s narrow profile and landing gear

placement provide pilots with an unobstructed view of the load

from either side of the aircraft for enhanced control and more

precise load placement.

An external instrument panel is strategically located outside

of the cockpit, enabling pilots to actively monitor performance

during load operations.

In addition, the K-MAX operates with a minimum number

of systems that require pilot action or monitoring. The pilot

can perform all normal and emergency procedures without

removing hands or feet from the controls.

InnovationThe K-MAX effectively marries new-generation technology

with an extraordinarily rugged airframe. Its aluminum fuse-

lage ranges in thickness from 0.065 inches to 0.125 inches for

enhanced durability and safety, especially in critical areas such

as the cockpit, fuel tank and lower fuselage.

The key to its efficiency is a distinctive,

oversized, intermeshing rotor system

with servo-flap control. The K-MAX

uses counter-rotating main rotors but

no tail rotor, so all engine power goes

directly to the large main rotors for

maximum lifting capacity. What’s more,

the K-MAX maintains its power and

performance at high altitudes and at

high temperatures, an important opera-

tional benefit that is directly attributable

to the aircraft’s superior design.

The counter-rotating, servo-flap controlled, intermeshing main rotors of the

K-MAX put all available power into lift, wasting none on anti-torque.

PILOT WORKLOAD COMPARISONWe put a lot less into the

K-MAX — complicating

systems and tasks — so you

get a lot more out of it —

more safety, more reliability,

and fewer distractions

during flight.

Each blade on the K-MAX is controlled by a servo-flap. Located about

two-thirds out on the trailing edge, they aerodynamically control

blade twist, and the pilot has a direct connection to them

without relying on hydraulic or electrical systems.

Profitability is the bottom line in any helicopter operation, and K-MAX has what it takes to be both effective and affordable. Its simplicity of design makes it easier and more cost effective to fly and maintain than some other helicopters.

For example, the K-MAX utilizes mechanical servo-flaps for

rotor pitch control, eliminating the need for high-maintenance

hydraulic boost systems. The lack of a tail rotor eliminates

two gearboxes, drive shafting and associated maintenance. In

addition to its reduced maintenance requirements, the K-MAX

requires less frequent maintenance and needs no special

facilities for maintenance work.

One pilot and one mechanic, and you’re ready to fly with

less than one maintenance man-hour required per flight hour.

The K-MAX also saves operators money on fuel, using just

82 gallons of fuel per hour during lift operations and delivering

the most efficient lift-to-fuel ratio of any helicopter in its class.

When it comes to productivity, no helicopter can outwork

the K-MAX. It will fly every day with unmatched reliability.

Numerous operators have flown more than 1,500 hours a year,

moving from fire fighting to construction — or any other

lifting mission required.
