Oct. 16, 2017, © Leeham Co.: President Donald Trump announced Friday he will decertify the Iran nuclear deal, throwing into doubt a host of related commercial deals, including huge aircraft orders.

Trump hasn’t gone so far as to withdraw from the pact, but he still threatens to do so unless Congress makes changes he wants.
Here in the US, focus is, of course, on the commitment by Iran for Boeing aircraft—none of which are firm contracts, but “commitments” to order.
Of less focus here, if any, is on the outstanding orders placed by Iran for Airbus and ATR aircraft, which are subject to US licensing.
Aug. 21, 2017, © Leeham Co.: Commercial aviation in the Middle East may be having its severe challenges right now, but over the weekend a major step forward took place.
Dubai Aerospace Enterprises over the weekend completed its acquisition of lessor AWAS. The combined companies will do business under the name DAE Capital.
It’s a milestone for both companies.
August 18, 2017, ©. Leeham Co: In this Corner, we will finish the design of the hybrid propulsion system for our 50-seat regional turboprop. We use the ATR42-600 as a reference, as before (Figure 1).
We found an acceptable redundancy concept in the previous Corner, with an APU+generator+battery as backup power source. Now we will finish the design of the hybrid propulsion chain and compare with the original turboprop propulsion.
August 11, 2017, ©. Leeham Co: In this Corner, we will design the hybrid propulsion system for our 50-seat regional turboprop. We could see in previous Corners that we can’t use batteries as a backup for our gas turbine core and main generator.
The battery gets too heavy as the specific power weight of a battery is simply too low. We will now design a hybrid power chain with a different redundancy concept.
August 03, 2017, ©. Leeham Co: In our search for an electric regional aircraft configuration, we found that a jet aircraft requires too high power levels. The higher speeds of a jet aircraft take the power levels beyond what we can handle with an electric hybrid propulsion system.
Our ambition is to transport 50 passengers on a regional network. For networks which have sectors around 200-300nm, the turboprop is the preferred regional aircraft. We will now re-direct our hybrid regional aircraft project to this market segment.
