The following technical information presented is considered "general information". Sensitive information about the design & construction of the L1 Vertical Wind Tunnel will be released to Pre-Qualified Buyers after signing a Nondisclosure Agreement with Vertical Wind Tunnel Corporation.

1. Site
   Size in Feet: approx 110 - 170L X 50W X 20T
   The overall shape of the site is rectangular, and the tunnel itself can be mostly buried.
   Length varies depending on the configuration you choose for your application.
    
2. Air Column
   Nozzle: 12.8 foot diameter
   Expansion of the column has been officially measured at 13 feet
    
3. Motor & Control Systems
   Manufactured by General Electric
   5 year Warrantee Included from GE
   Custom Order- Lead Time 12 months
    
4. Sound Measurements
   Exit from 35 ft away:
   -500 rpms under 80 db
   -650 rpms under 95 db
   Exit from 2 ft away:
   -500 rpms 110db
   -650 rpms 115db
   Inside Motor Room:
   -500 rpms 90db peak/80db average
   -650 rpms 90db peak/85db average
   Spectator Area: 66 ft away
   -500 rpms 78 db
   -650 rpms 83 db (quiet enough to carry on a cellphone conversation)
    
5. Airspeed Readings (Averages)
   550 rpms = 110 mph
   575 rpms = 115 mph
   600 rpms = 120 mph (our most commonly requested speed)
   650 rpms = 125 mph
   675 rpms = 128 mph
   700 rpms = TBA
   720 rpms Max RPMs = TBA/+-140 mph expected
   Average airspeeds must be calculated as the temperature & density of the outside air can dramatically affect the air column in regards to speed.
    
6. Power Consumption
   550 rpms = 45.1 %
   575 rpms = 50.6 % (Half Power)
   600 rpms = 57.1 %
   650 rpms = 66 %
   675 rpms = 70%
   700 rpms = TBA
   720 rpms Max RPMs = TBA/+-140 mph expected
    
7. Efficiency is the measure of how much energy goes in, compared to the work that is done. To a VWT operator it is how much fuel is used to produce the jet (flight area). A wider or faster jet has more energy and so requires more power to produce. Basically, if the jet has 1000 kW of energy, and the VWT is 70 % efficient, a 1300 kW motor is required. A less efficient VWT will require a larger motor and so costs more to operate per hour.

This L-1 is at it's highest efficiency at it's design speed of 120 MPH, which is more than adequate for flyers at all stages.  L1 can be adjusted to optimal efficiency at other airspeeds depending on your application.
