~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1. What kind of car is this?
This is a car we have built to challenge the world land speed record for automobiles. It is in the Unlimited Class. It is a form of racing where competitors drive their cars through a measured mile twice, each in opposite directions (to compensate for any tail wind advantage). The average of those two runs determines the final speed of the vehicle.
2. How fast does this car go?
Our present car has not begun speed runs. We hope those will commence some time in 2004. Our prototype vehicle conducted low speed test runs of 300 mph. The speeds are low because we had did not have our high speed wheels at the time.
3. Are you guys trying to break the sound barrier?
Andy Green set the current record at 763.035 mph, which converts to Mach 1.02. The current world land speed record was certified by USAC and the FIA at Mach 1.02. The two runs were officially reported as Mach 1.015 and Mach 1.02, and the 2-way average was
stated as Mach 1.02. To break the record the rules require that it be at least 1% faster, or roughly 770 mph. Depending on temperature, it will most likely break through the sound barrier.
4. Is this a rocket car?
Maybe. The main powerplant is a J-79 turbojet jet engine. It originally was used in the Phantom F-4’s. We are looking at utilizing a small 6,000 lb. thrust liquid propellant motor for added boost. It may be needed to get the inertia started on the North American Eagle. Performance Data conducted by Wayne Olson shows that we will need 3 1/2 miles to get to 800 mph. The additional thrust of a rocket motor would certainly shorten this.
5. Who is the driver?
Ed Shadle is our test driver. Ed has experience in land speed racing. He currently holds the B Street Roadster class record.
6. Why the Canadian Flag?
We realized about a year and a half into the project that many of our vendors, including team member Steve Green were from Canada. That is why we call the car the North American Eagle™. The name was brainstormed from a list generated by Keith Zanghi and Ed Shadle. The team has protected the name by having it trademarked.
7. Are you going to run the car at the Bonneville Salt Flats?
We can do slow to medium speed testing at Bonneville, up to say around 500 mph. The problem with the salt flats is it’s too short. Every year because of the floods, the length of the available run area shrinks. Last summer only about 7 miles was usable. We need about eleven miles to run the car at record speeds.
8. Where then will you run this car?
We are currently considering two venues; Black Rock Desert in Nevada and, perhaps, southeastern Oregon, if investigation of the location and accessibility is feasible.
9. How much does this car cost?
It would take about $10,000,000 dollars to build the car today, which includes developmental, engineering and non-recurring costs.
10. How much power does the engine make?
With extensive modifications, the J-79 we have makes about 39,000 hp.
11. How does that compare to real cars?
The car weighs about as much as the Hummer, about 6,500 lb., but instead of the approximately 180 hp V-8 engine under the hood, the North American Eagle™ has 39,000 hp! In the Movie War Wagon with John Wayne, the stage coach Wayne drove would have a tandem set of horses extending 45 miles in front of the vehicle!
12. What kind of fuel does this car use?
The engine uses JP-4 jet fuel.
13. What kind of mileage does this car get?
In full burner this car consumes about 10 gallons of JP-4 jet fuel every second! It consumes 138 lb. of air in the process. In one mile this car burns 50 gallons. When you do the math it works out to .02 miles per gallon, or about 105 feet per gallon!
14. How fast will this car do the quarter mile in?
This car is heavy, and takes a little while for its massive weight to get moving. Once it does, it starts pulling about 2 1/2 Gs throughout the run and will make up for the quick start of a Top Fuel Dragster on the other end.
15. How fast has this car gone?
This car has not run yet. As an aircraft it has traveled 1,200 mph. When testing commences, initial runs will be run at local airports up to 300 mph. This is due to the aircraft tires we use, are limited to 300 mph.
16. If the tires are only good to 300 mph, then what will you use?
We have specialty design wheels capable of 900 mph. The initial design was verified using FEA (Finite Element Analysis). The wheels are manufactured entirely of aluminum, machined from a solid block of billet. The design is the accepted standard being used by world landspeed record challengers today.
17. Is this the record holding car?
No. Andy Green set the current record on October 15, 1997. He made a two way average speed of 763.035 MPH. The owner of the car, Thrust SSC, is the former world land speed record holder Richard Noble, from England. He set the record on October 4, 1983 in the Thrust 2, at the Black Rock Desert in Nevada. We’re building the North American Eagle to challenge the current record.
18. How much steering is involved?
When you look at in-car cameras, the steering of the car is quite extensive at lower speeds, even though the travel of the front wheels only move about 2 degrees right or left. When Andy Green was driving the ThrustSSC, he had his hands full keeping it on course between speeds of 450 mph to 600 mph. Perhaps this was due to the aerodynamics of the ThrustSSC and we can only hope the NAE doesn’t have similar problems, but we’ll find out. To view this, go to the classroom section of this site and find the link for downloading a video clip of the ThrustSSC on one of its runs; in it, you’ll see the video black out during the “trans-sonic” speeds between 450 & 600 mph. Once the picture returns you’ll notice the run line is off to the right and can hear Green talking about having to pull it back on course to get it on the line again.
19. Can you drive this car on the street?
No. The state patrol and county police have problems with cars that shoot 70 foot flames from the tailpipe!
20. What practical applications if any, does this car have to the real world?
Two examples come to mind. The first is parachute deployment tests. Results of these can be used in the design of spin recovery chutes for fighter aircraft. The second is the study of high speed vehicles near the surface, such as high speed rail transport.
21. How do you stop this car?
Five systems are used to bring the car to a stop. At the end of the measured mile, the driver pulls back on the throttle, in doing so he deploys a small drogue chute and speed brake doors on each side of the vehicle will be applied. These speed brakes are side doors on the fuselage which are part of the F-104 design and are hydraulically actuated outward on each side near the rear. When the car slows to 300 mph, the main chute is deployed. This slows the car to approximately 125-150 mph, at which time the disk brakes (rear wheels) can be applied. If all or part of these systems fail, the driver can steer the car into an aircraft carrier catch net which has been tested to 300 mph.
22. Didn’t a car in the past once break the sound barrier? (submitted by J. McKee)
On December 17, 1979, Stan Barrett driving the Budwieser Rocket Car owned by movie producer Hal Needam and William Frederick, ran a reported speed of 739.666 mph (this equals Mach 1.0106). This run though was never recognized as an official land speed record for the following reasons: It was only a one way run. The rules require two runs, each made in opposite directions, within an one hour time limit. This is done to compensate for any tail wind advantage the car may have in either direction (just like football!). Second, the Budwieser Rocket Car only had three wheels, whereas the rules require a minimum of four. Third, the timing was calculated using radar supplied by the Air Force. The rules require the timed run be done on a measured (and certified) one mile section and fourth, the entire event must be coordinated by the official sanctioning body, FIA.
In spite of all this, it was a magnificent engineering achievement that received world wide coverage and courage by driver Stan Barrett. Peter J. R. Holthusen in his book The Land Speed Record has a well written account of the event. Your local library will have a copy. The Library of Congress number is 86-81747. Good Question!
23. What is the current Land Speed Record? ( submitted by J. McKee & Charley Schaffer)
The current record is by Andy Green in the Thrust SSC at 763.035 MPH on October 15, 1997. The *previous* record was *also* set by Andy Green in ThrustSSC, on September 25, 1997, at a 2-way average of 714.444 mph. This record was ratified by USAC and FIA, as was the most recent one of October 15, 1997.
See:

http://www.cnn.com/TECH/9709/25/land.speed.record/
The previous record to Green’s Sept. 25th one was held by Richard Noble in the Thrust 2 at 633.468. This was set on October 4, 1983 at the Black Rock Desert in Nevada.
24. Is there anyone else trying to break the record?
There are currently three teams with equipment to go after the record. The person with the best chance is probably Craig Breedlove from Rio Vista California. Driving the Spirit of America, Craig is fielding a well manage team that will try to set the record when repairs are made to his vehicle.
