Kerbus' latest line of aircraft in the medium-haul jet category, offering competitive performance at market-leading fuel efficiency.

This is an example of an aircraft that would score highly in the medium regional jet category.

Test Pilot Review: Kembraer. - ZO-135

Figures as tested:

• $12,490,000
• Fuel: 200/200 kal
• Cruising speed: 296 m/s
• Cruising altitude: 11,000m
• Fuel burn rate: 0.05 kal/s
• Range: 1180 km
• Mass: 9.705t
• 19 Parts

Review Notes: The Krembraer ZO-135, while unconventional, is one of the most exciting small regional jet offerings we've seen so far. It's canard design is inherently self-stabilizing, and it's center fuel-tank, while oddly positioned between passenger spaces, ensures that weight distribution remains centralized as fuel is burned. With only one engine, maintenance costs are reduced. And it's fuel-sipping 0.05 kal/s efficiency at a respectable speed of 296 m/s is highly competitive, if not market leading. Its light weight and simple design reduce landing stress and wear on the fuselage, while lowering maintenance costs. Lastly, its $12,490,000 pricetag means we can purchase nearly twice as many aircraft at the same price. We're so confident in the ZO-135, that we're immediately leasing ten aircraft as a service trial, with the potential to purchase up to 50 aircraft should it perform well in service.

Our verdict: The Krembraer ZO-135 performed excellently, besting the competition in every way. As of this review, it stands as our #1 pick for a small regional jet replacement.

After it was pointed out that KerbAir's first medium-range regional jet had twice the passenger capacity required, we scrambled to find a replacement submission. Now we are proud to announce our Econoclass medium-range passenger jet, the Flopping Dolphin!

This is definitely the jet for airlines on a budget. At a little over $19 million, it is priced far below any other medium-range jets and below most short-range jets. Seating is admittedly cramped, with the central economy cabin lacking direct window access, but the single engine in the tail means very little cabin noise.

Detractors argue that having two cockpits is unnecessary, but our engineering department assures us that the redundancy of two separate cockpits is an added safety bonus. Our acquisitions department also indicates that having two separate flight decks is actually less expensive than one larger two-seat cockpit.

The taildragger orientation keeps the nose pointed up for shorter takeoffs, and the V-tail further reduces costs.

Takeoff with flaps (AG1) is achieved below 80 m/s.

With a cruising altitude of a little over 4 km, cruising speed of 247 m/s, and a range of 1,600 km, this jet is just within the requirements of a medium-range regional jet. But its low part count and low fuel consumption means it is very affordable to operate, at $0.50 per passenger-km for fuel costs.

Ok folks! Submissions are now closed!

You may still discuss reviews and designs as the Kerbal Express Air test pilots finish reviewing entries.

damn it, i just missed it 

[NISSKEPCSIM]

Argh! I was just about to begin the maiden flight of my airliner when I saw your above post!

[tsgaerospace]

i put work into it and mainly tested it for about 25 minutes so i´m going to upload it anyways even if i don´t get in the challange

company: TSG aerospace

name of the plane: SP-32-1 "Arrow"

cost: 17418000

part count: 45

mass: 10.753t

range: 1556.775km 

coasting altitude and speed: if fuel is over 300 units the coasting altitude is 6625m and if below 300 units 8000m
max speed at 6625m is 291m/s and at 8000m  280m/s

notes: tweakscale was used just for the air intake, nothing else

i only went ½ of the maximum range, i just got bored but some simple math tells you that the maximum range is 1556.775km 

the TSG SP-32-1 "Arrow" is a relatively cheap and low maintanence turbofan airplane capable of transporting 32 kerbals over 1500 km, it uses 0.11 units of fuel on the high end and 0.08 units on the low end, it´s easy to fly, highly maneuverable and includes flaps and an engine capable of retroburning to help with landing. the TSG SP-32-1 "Arrow" is a smart choice for anyone who needs to take up to 32 kerbals to the other side of the world !

do not taxi at over 45m/s or you will face takeoff

Do you mind if you tell me where that cockpit comes from? It looks like a Mk1, but without the nose cone.

[tsgaerospace]

it´s from the airplanes plus mode, along with most of the wings

and the passanger door is also from the mod

i´m sad.

because of a power outage i missed the deadline because my internet didn´t work ):

[ImmaStegosaurus!]

Oh boy, I missed the deadline. 
 

Spoiler

Could turboprop aircraft have competed against pure jet designs if they could fulfil requirements set for jets?

I'm curious to see if any more tests are planned.

Keptin might be busy at the moment.

What? A deadline? NOOO! And I had JUST built something!

I tried. Didn't go well.

[keptin]

Hey peeps, more tests are planned, I've just been swamped with work. Maybe tomorrow.

Russians managed it. It has to be possible. IMO it's preferable. Za Stalina!

This challenge looks like a ton of fun, I hope someone starts it up again soon. 

[TheEpicSquared]

@keptin Are there any plans to get this challenge back online sometime down the road? If not, may I reboot this? With your permission, of course.  

[tsgaerospace]

if yes i will try to not miss the deadline by 57 minutes...

There won't be a deadline if I get permission to reboot the challenge

Just go ahead and reboot it. He said it was open for someone else to reboot.

But you should add some new requirements. Not so much to make it onerous, but perhaps a few other things to optimize for. For example, you could make the cost be dry cost, not fueled cost. You could class by cost rather by range, speed, or crew capacity. You could include supersonic options or wider-ranging executive/express jets.

[TheEpicSquared]

I'll try to get it rebooted tomorrow. Suggestions and the like are appreciated

Definitely lower kerbal requirements for planes because kerbal crew cabins fit less kerbals that IRL ones fit people.
