Post SFS NEws: TAAS Company Discuss Their Safe, Economical and Ve   Posted on: Fri Dec 05, 2008 4:46 pm
I recently got talking with Robert Talmage of the TAAS Company. I had earlier read a paper introducing their modular escape vehicle. Speaking with Mr Talmage I asked him a series of questions about their plans to develop their vehicle. We discussed their plans to reach suborbital space and scale this up to orbital flights, Mr Talmage also provided details on the safety aspects considered in their designs. See the Escape Vehicle (EV) on the image below.

The idea behind the design is that the escape vehicle leaves the parent vehicle behind in the case of an emergency, it does this in conjunction with multiple plug-in devices and one mechanical release which allows the EV to slide forward and un-plug from the parent vehicle. Air-bags can provide positive separation forces. “After separation, the EV (which is designed to fly at higher dynamic pressures than the parent vehicle) will naturally pitch down and accelerate. Releasing the forward weight of the EV will cause the parent vehicle to be out of balance. With the center of gravity now well behind the center of lift, the parent vehicle will be unstable and pitch up. The high drag configuration of the unstable parent vehicle will provide good horizontal separation from the EV.â€

Post TAAS Company Escape System   Posted on: Mon Dec 08, 2008 12:44 pm
Rob, I wanted to try and clear up some issues about the article on the TAAS Company escape system that have come up.

Our US patent (# 6,776,373) was issued August 17, 2004 and the provision patent precedes that by another year.

The unique aspect of the TAAS escape cabin over the F-111 and other cabin ejection systems is the attachment technique and gliding capability.

The article discusses our presentation made May 1, 2008 at the AIAA International Space Plane Planes and Hypersonic Systems and Technologies Conference in Dayton, Ohio. The paper (A Safe, Economical and Versatile Space Flight Test Vehicle, #AIAA-2008-2659) discusses how our escape system compares to other escape systems and then outlines a proposal to demonstrate our technology.

The proposed project to demonstrate the escape cabin involves modifying an old Learjet. The proposed four million dollar cost would demonstrate the escape cabin and then the aircraft would be available to operate as a flight test vehicle. At this point the plan is to acquire additional funding to incorporate rocket engines and operate the modified vehicle as a sub-orbital space flight test vehicle.

The objective is to use this flight test vehicle to explore new sub-orbital trajectories and produce revenue as a space flight test vehicle. The concept can be scaled up to eventually fly orbital missions but this will be accomplished incrementally with progressive vehicles. Contracts, sponsors and revenue from the flight test vehicles will fund each new vehicle which will provide the data necessary to develop the next generation space planes.

I hope this clears things up.

Many Happy Returns,

Robert Talmage
