I don't know anything about the plane, but just saw an announcement that the Aerostar jet will be at OSH.

Tom,

Very attractive aircraft. It's the first time I have seen one.

Do the engine mountings create any special FOD issues.

No TRs, no spoilers, you will need to change the brakes every other landing or just shut down an engine at touchdown to keep from going off the end of anything less than 5K feet.

The current type certificate holder, Aerostar Aircraft, is doing this project. IIRC, they are working on an STC for the piston to jet conversion. I don't know about braking, but Gary's 700P has spoilers.

He may have sold his Aerostar. If so, that means he's shopping!

Drag chute! :hide:

It did look like that thing was zippin' along pretty good at touchdown. Wouldn't be pretty on a slick runway or with a tailwind component.

Depending on the weight, approach speed for the Aerostar with recip engines is about 90-98 kts. Landing distance over 50' obstacle at ISA conditions, no wind, max gross wt ranges from 2150 sea level to 2800 at 10k ft. Full flaps, stall touchdown. My guess is most carry a little extra speed, but I doubt anyone would need 5000'.

Hi Fred, Just an educated guess from years of flying jet equipment? I will be happy to eat crow if I am wrong as the Aerostar line and anything Ted Smith designed has been a favorite of mine since I was flipping through the pages of my Dad's issues of "Flying" magazine.
However, in watching the video provided there did not appear to be any TRs on the engine cowling and after touchdown there was no engine spool up to indicate TR deployment. I did not see any spoilers deployed after landing either. Landing flaps seemed to be the same setting as takeoff flaps. Since there is no prop to energize the air flow over the wing I would expect the landing speed to be bumped up a little over the piston version as well as to help with spool up time (depending on how much electronic help the engines have)

The biggest reason I made my comment about brakes and roll out is the residual/idle thrust of a jet/turbine engine. I would expect that the FJ-100 would have at least 1000# per side to equal/better the thrust available from the prop version and probably more to insure adequate performance at altitude since a turbine/jet engine is normally aspirated and has the associated power loss with altitude. At idle with a jet you are still getting a healthy push. (Looking at your company info I expect you know this and some of this is for other readers that may not have turbine/jet/turbofan experience. Not trying to talk down to anyone.) With the 737-500/700 series there are many time that you don't need to add power to taxi away, just release the brakes and wait a second or two and it will move on idle power alone then you will need to keep taxi speed in check with brake application.

The FJ-100 with single disc, no anti skid, no props going flat with power reduction at touch down, no spoilers to put weight on wheels, no TRs to help reduce the idle thrust and kill off the first 20-30 kts or so of speed will have to have a longer roll out than the prop version of the Aerostar, no doubt about it. Is it a bad thing, not really, if you have a long enough runway, don't over heat the brakes or flat spot/blow out a tire.

Bob

It's also going to be a FOD collector par excellence. Looks very cool, but I think there's a good reason that virtually 100% of existing business jets have the intakes above the wing.
