 Rolling
Hills Research Corporation is a closely held, high-tech aerospace
company based in El Segundo, California. RHRC was formed in 2002,
continuing a
tradition of innovative research started in 1982, and we are the
sole provider of the former Eidetics®
brand of water tunnels. RHRC also offers a wide range of aeronautical engineering,
computational fluid dynamics, and
simulation expertise.

University
Desktop Water Tunnel
 The
University Desktop
Water Tunnel is the latest addition to our line of water tunnel
products. The University Desktop
Water Tunnel is ideal
for in-classroom demonstrations and student research projects. Prepared Classroom
Experiments are also available. The Model 0710 now also includes an
easy to use feature that clears bubbles from the flow conditioners for
optimum flow quality.
A complete description of the Model 0710
is now available for viewing and download.
Research
Water Tunnels  The
water tunnel has always been recognized for its outstanding flow
visualization capability, and now it can be used for low cost force
and moment measurements. RHRC's water tunnels can be used for static
and dynamic experiments. The research water tunnel comes in
two sizes: the Model 1520
and the Model 2436.
Both tunnels are now available in
extremely corrosion
resistant versions that minimize the use of
any metallic components in contact with the working fluid. This
makes the tunnels ideal for research using fish and marine creatures
because saltwater can now be used as the working fluid.

1-Component Balance  As
a compliment to the Model 0710 University
Desktop Water Tunnel, the 1-component balance
introduces students to data acquisition, tare procedures, and
calibrations. It also helps the student to correlate what is
observed with flow visualization. For additional information,
please download the 1-Component
Balance Description in Adobe Acrobat format.
RHRC
Continues Innovative Aeronautical Research
Phase II SBIR to develop and validate
a robust flow control design approach
for natural laminar flow airfoils that vastly improves performance with
minimal power requirements.
Phase III SBIR to measure the
non-linear aerodynamics of the F-16XL for NASA Langley Research Center
(LaRC). The water tunnel is equipped with a submersible 5-component
strain gauge balance and a computer controlled, dynamic model support
system. The system provides an inexpensive method for obtaining
damping derivatives, rotary-balance data, and other information normally
only available through expensive wind tunnel testing.
2010 and beyond:
Several new proprietary research programs are currently underway in the
areas of drag reduction, natural laminar flow, flight safety, and flow
diagnostics.
