Rolling Hills Research Corporation


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, the latest addition to our line of water tunnel products, has just been  improved for 2014.  The University Desktop Water Tunnel is ideal for in-classroom demonstrations and student research projects.   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.

 

New! The second generation of the popular prepared Classroom Experiments are now available.

 

 


Laser Doppler Velocimetry (LDV) - RHRC is pleased to offer advanced laser measurement products for use in water tunnels. The LDV verifies that the velocity profile in RHRC's tunnels is the highest quality in the industry. Contact us for more information.

 

          

Advanced LDV requires no alignment

LDV verifies extremely uniform flow in test section


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 coupling of simultaneous flow visualization and force measurement provides powerful insights. The research water tunnel comes in two sizes:

the Model 1520 and 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.

Please read a detailed description of our Research Water Tunnels and the types of experiments that are possible.

 

RHRC can also build custom water tunnels to your specifications.

1-Component Balance  

Eidetics One-Component BalanceAs 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

 

NARI LEARN Phase II research program into a Turbo-electric Distributed Propulsion Test Bed Aircraft is underway.  This project investigated replacing a single engine with a distributed array of boundary-layer ingesting propulsors. In a large scale transport aircraft, this approach, mated with a hybrid blended wing body design, has the potential to deliver revolutionary efficiencies. A briefing of the Phase I final results can be downloaded here.

 

Phase II STTR teamed with the University of Illinois to develop an aircraft flight envelope monitoring system that will provide real-time in-cockpit estimations of aircraft flight envelope boundaries, performance, and controllability. The adaptable monitoring system will provide information on current and predicted aircraft performance and controllability, alerting the pilot to any aerodynamic degradation of the control effectiveness. This includes high angle-of-attack, heavy rain, in-flight icing encounters, environmental contamination of surfaces, and structural or battle damage.

 

Phase II SBIR to develop a self-contained, self-powered, robust flight test sensor array for the determination of separation.  This program has successfully developed the separation detection array, which has been tested in flight and in the wind tunnel.

 

2014 and beyond:  Several new proprietary research programs are currently underway in the areas of drag reduction, electric aircraft propulsion, flight safety, and flow diagnostics.
