From Sarah B. BMI Racing, taken from RX7 club:
Hi All,
I'm not usually the type to post anything on forums, but I will have to get used to this with the car that we are building. I am part of BMI Racing, and we are in the process of putting together an RX8 4 Rotor, it is something that we have been working on for quite some time. I would like to take this opportunity to thank SVEN at NRS SEALS for providing the 2mm 2 piece apex seals for the engine, Sven did a wonderful job at ensuring that these seals we top notch. You may have seen his link from a few days ago of the engine running. I would like to let you all know that I will start a new thread soon giving you some information on the setup and a few pictures also - in saying this can someone please let me know where a suitable place would be to post this.
Thanks
Sarah

Default It just keeps getting better and better

As you know we are always striving to improve the quality of the final product. I am happy to report that we have refined our annealing process to offer the highest increase in fracture toughness possible. This takes our material to even greater heights as we redefine once again the record books on what is acheivable with this material. Our results have yeilded an increase in toughness of 1.5 MPa over and above the earlier reported figures. This sets NRS ceramics miles above the rest.

Our testing is done with the most accurate methods accepted. 4 point bend, notched with a very sharp crack induced at the bottom of the notches. It is important to have the sharp crack on the bottom of the notch for the most accurate measurement, otherwise a higher value would be noticed.

This testing yeilded a fracture toughness of 11 MPa +. With proper annealing this value could exceed 12 MPa to possibly 12.5 MPa

We noticed from a sample with slightly different processing an increase from approx 10 MPa up to 11.5 MPa with the refined annealing process. The latest material starts at 11 + MPa so we would expect to see a similar increase and should yeild upwards of 12 MPa + as noted above.

Where does this put NRS material in relation to others? Most other like materials fall into the 4 - 6 MPa with 8 MPa being about the top.

Default Update from Cubewano

I just spoke to Cubewano regarding the ceramic apex seals used in their UAV engines. After 250 hours run time they could not measure any wear at all to the apex seals. Measurements were taken in a temperature controlled room using a digital micrometer. Not even 0.0001", a tenth of a thou, was noticed. The seals are run on Nikasil housings. This is really quite an amasing result and we are very pleased to be working with Cubewano on their rotary engine power plants for UAV's.

This just came in from Toru Tokoyoda:

Hi Sven,

http://speedhunters.com/archive/2009...le-rocket.aspx

your ‘spotty’ seals held up well. No issues at 235+ mph in 2009.

2010, the car went airborne at 240mph, so we will need to rebuild the car.

Default NRS Powered N/A BP 13B R100 Australian Record

Just in from Matthew Rice:
Hi Sven
Just to let you know that on the second full pass in the R100 we have taken the record here in Australia ( quickest and fastest N/A 13B

Our aim is to be the first 9second 13b in Australia

10.1 @ 130mph

13B Bridge Port (of course with NRS seals)

I have attached a photo of the car and a link below to the video

Thanks again for the help with the seals (I trust you received the magazines I sent with your press release Fast Fours / Hot Fours)

If you sent a couple of small stickers I may even be tempted to put them on the car hahaha
