Volna Engineering Company
 

For the past forty years, Volna Engineering has provided one-of-a-kind
solutions to difficult measurement and tooling problems for the aerospace and
defense industries. Significant trademarks of Volna Engineering design embody
the principles of "kinematic coupling," as follows:

  • Any free solid body has six possible degrees of freedom in space
    -- three of translation and three of rotation.
  • If a body has six degrees of constraint, it has no freedom.
  • If a body has more than six, a condition of stress exists
  • Removal of constraints, one at a time, allows additional degrees
    of freedom for a specific task in any machine or measuring instrument.
  • A machine element with one necessary degree of freedom and more
    than five degrees of constraint will have uncertain performance (hysteresis),
    higher friction, and higher cost.
 

If you are currently planning a device, product, or machine
that must possess high precision performance for the least cost,
consider the use of "kinematic coupling" design principles.

Products of Kinematic Design

The following photos of Volna Engineering products are examples
of kinematic design that have successfully stood the test of time
with undiminished performance:

 
  • Gyro Test Table
    Embodying the principles of "kinematic coupling," these roll-tumble,
    two-axis test tables were built for the final calibration testing
    of Honeywell ring-laser navigation systems and have been in service
    for 19 years with unchanging sub-arc-second accuracy.
  • VTAS Nonmagnetic Head Tracker Accuracy Test Station
    The first requirement of this Visual Target Acquisition System (VTAS) device
    is magnetic transparency. Linen phenolic and epoxy are used to fabricate
    the main frame. The x, y, and z "ways" are optically polished
    glass, straight within 10 arc-seconds. Kinematically constrained ceramic ball spindles
    provide arc-second accuracy after 18 years of service.
  • VTAS Roll Pitch Helmet Fixture
    Designed for the Armstrong Laboratory, Wright Patterson Air Force Base,
    this Visual Target Acquisition System (VTAS) fixture provides two coincident
    axes of helmet rotation about a simulated tragion (top of the spinal column).
  • Head Tracker Accuracy Test Station
    This device was produced for the U.S. Navy F-14 fighter aircraft.
  • Air Bearing Nonmagnetic Flight Simulator
    Designed for UNISYS, this device is an example of three degrees of kinematic constraint.
 

Other Products

  • Solar Energy Research
    A two-axis solar tracker, which requires less than 10 watts to drive it,
    produces 2 kilowatts of heat energy, and heats 100 gallons of water
    to 100 degrees F. in 8 hours of daylight. Behind the control console
    are two solar stills, each of which alone desalinizes
    18 gallons of salt water on an October day.
  • Environmentally Controlled Portable Astronomical Observatory
    Designed and built for use in hostile climates.

Volna Engineering Facility

 

Volna Engineering is a sole proprietorship founded in 1968 in Minneapolis,
Minnesota, by William M. Volna, a graduate mechanical engineer. The 4,000 sq. ft.
company-owned facility (below) contains a wide selection of lathes,
milling machines, grinding machines, and welding equipment. Computer-aided
design is used in all design drawings and documentation.

In a separate facility, Volna Engineering has added an optical fabrication
shop with a 16 in. diamond curve generator, several Strasbaugh polishers,
a 16 ft. optical bench, a 21 in. vacuum coater, a 35 in. vacuum coater, and
an 18 in. Zygo interferometer.
