PORTABLE STORAGE SOLUTIONS FOR
R44 HELICOPTER OWNERS
GENERAL DESCRIPTION:
Traditional hangars used by helicopter owners are fixed
structures, requiring planning permission. Lindstrand
Technologies Ltd has developed a series of inflatable
hangars, which are used as temporary units, and can
be seen in operation by the RAF, Swedish Air Force,
SAAB and the US Marine Corps.
FEATURES: Air cell buildings are self-supporting and self erecting. They are fabric structures
with little or no hardware, which means they will pack up into a small volume for
ease of handling and transportation. The R44 hangar can be installed and inflated
by a 2 man team in 30 minutes and deflated and packed away in one hour. No
tools or lifting equipment is required – simply connect the air fans and watch the
hangar inflate.
Fans used in these buildings operate on full power during initial installation, but
once the building is fully installed, the control system will switch to intermittent
mode, governed by pressure sensors, typically operating for 10 seconds every 5
minutes.
R44 HANGAR DETAILS:
The R44 hangar supplied by Lindstrand Technologies Ltd would comprise of 2 inflatable units and an
‘eyelid’ door.
The dimensions are 15.48 m long x 7 m wide
(external) x 4.0 m high (internal). There can be
personnel access doors along the length of the
building and hook up points are incorporated into the
building to allow the integration of lighting or air-
conditioning/ heating systems.
These hangars are designed to withstand up to 80 knots wind speed, and have been proven in service.
The anchoring infrastructure of the building will depend on the surface type at the client’s location, but will
typically be either ground earth anchors (sand/ fine soil), earth screw anchors (heavy/ clay soil) or anchor
bolts (concrete).

CLASSIFICATION: The R44 helicopter hangar is classified as a temporary structure and does not
need planning permission – only land owner’s permission to install. The hangar
complies with all published regulations for inflatable buildings.
INSULATION: The hangar is built from two parallel layers of fabric with fabric formers
perpendicular to both surfaces. This will give a condensation free interior and
good insulation. The U-value is 2.2.
FABRIC: The hangar fabric is a military grade PVC coated polyester and complies with
fire retardancy regulations under BS 7835/ 5438 and for anti fungal properties
(MIL-STD-810E). Most customers choose either desert tan or olive drab but
almost any colour can be supplied.
SURFACE
PREPARATION:
The R44 hangar can be installed on almost any surface: concrete, tarmac, grass
or compacted earth. The hangar is secured to the surface by ratchet straps
originating on load patches on the skin of the hangar and terminating at earth
anchors.
COST &
DISTRIBUTION:
The hangar typically costs in the region of £35,000 (GBP) or $55,000 (USD).
The hangar is manufactured in both LTL’s UK and US factories.

Bare Hull Resistance
To solve for the resistance of the vessel, equations were used from Ship Resistance and Propulsion, F.
Molland (2011) and experimental resistance data was obtained from Maritime Technology Monograph
No. 4 The NPL High Speed Round Bilge Displacement Hull Series.
Resistance Correlation
Based on Hydrodynamics of Large Motor Yachts: Past Experience and Future Developments research
paper for yacht design, optimum B/T, and B/L values were chosen. Using the results from the
preliminary weight estimates and our design speed we were able to obtain a desired length, breadth,
and draft to base our hull design on.
Designed hull characteristics (some values obtained from NX):
LWL=63.17m BWL=11.31m TWL=5.1m Vol=1572.48m3 SWS=847m2
L/B=5.585 B/T=2.2176 L/Vol1/3=5.4323
CB=0.4316 Cm=0.6155 Cw=0.7838 CP=0.7012
Comparing these hull parameters to series data, we found that the NPL hull was best suited for our
vessel. Below is a comparison of the coefficients:
Using the resistance tables for the NPL series in Ship Design and Construction Table A3.16 and also
confirming values found in Maritime Technology Monograph NPL series information, the following CR
values were interpolated for our vessel’s specific B/T and L/Vol1/3:

The following equations were then used to solve for the effective horsepower:
Using the ITTC 57 method for calculating frictional resistance and ship total resistance, assuming that
Sea water is at 9C and the model tests were done at 15C:
������ � ���
������ � 0.075�log�� � 2��
Assuming a surface roughness height for steel of �� � 0.0003� and using Townsin (5.7):
��� � �44 ����� ��/ � 10���/� � 0.125� ∗ 10
NPL model tests wer performed with w model of Length = 2.54m. Relating this to the actual ship results:
��� �� � � ���� ��� ��/�
���� �� � ��� ����� ����� ��
���� ��� 0.075�log ���� �� � 2��
Estimation of a form factor for the model to vessel comparison was then done. Using Couser et. al.
(4.27) suitable for round bilge monohulls and catamarans:
�1 � �� � 2.76��/�"#�/��.� � 1.4025
This was also compared to form factor graphs in the Maritime Technology Monograph NPL series data
and it was an expected result.
The overall bare hull drag coefficient for the ship was then solved for (5.6):
������ � ������ � �� � � $���� ��� ������% � ���
����� � 12������&'��
()������*� � ������/1000
Appendages:
Appendage drag was estimated by using empirical data and fits to estimate drags based on the designed
hull. NX was used to model the appendages and also estimate the appendage sizes. The appendages
added to the estimation were: 2 rudders, 2 skegs, bow thruster, and the superstructure wind drag.
Appendage drag was solved for using the ITTC method with the following table referred to:
Wake Deduction
The advance velocity was necessary for many appendage drag estimation. To solve for the advance
velocity, the wake deduction was approximated by using Taylor (8.14) for twin screw vessels:
+� � 0.55�� � 0.20 � 0.0374
�� � ��1 � +�� Rudder
Rudders were first sized using NX and the maximum available space based on the transom. The span b =
2.6 m, chord c = 1.78 m, aspect ratio AR = 1.46. The wetted surface area was then
'�� �� � 2,- � 9.26��
From Table 3.5: (1+k2)=2.8 for twin screw, balanced rudders.
/�� �� � 12&�������1 � ���'�� �� ��
/�� ������� � 2/�� ��
Skegs
Using NX to model the skegs, the following parameters were obtained:
Thickness t=0.3m, Surface area S=39.4m2
From Table 3.5: (1+k2)=1.8 for skegs.
/���� � 12&�������1 � ���'������
/��������� � 2/����
Thrusters
According to the ITTC method, bow thruster drag can be approximated as:
��� � 1&���2�����
With dT=Thruster diameter=0.8m as specified and CBTO=0.01 as a typical assumed value shown in the
text.
Air drag
According to the ITTC method:
��� � 0.001�3�' � � 0.00022
S being the wetted surface area and from NX: AT=187.94m2. Air drag was then solved for:
/��� � ��� 12&'��
Total Drag:
To solve for the total drag, the individual drags were added to the bare hull resistance for the
corresponding speeds.
/����� � /��� � ��� � /��������� � /�� ������� � �����
The effective Power could then be solved for:

Below is a plot of the results showing the bare hull resistance and added appendage resistance. Note,
the appendage resistance accounted for approximately 9-11% of the bare hull resistance which is an
expected range.

Propulsion: Propellers were selected by first consulting Bp-delta charts to iterate and size a suitable propeller. Then
KT-KQ charts were used with deductions to account for an ice class propeller.
Thrust Deduction
To solve for the thrust deduction, the Holtrop formula for twin screw vessels was used (8.26):
� � 0.325�� 0.1885 �√�� � 0.076967
Which was also close to the experimental graphs presented in the Marin paper, so it was an expected
value for this hull form.
The equivalent thrust could then be solved for:
� � ��
1 �
Thrust Power
Next, the thrust power required by the propeller was solved for:
�� � ��� � 1346.12�� � 1805��
Power per screw:
������ �
��2 � 902.6��
BP-δ Selection
For our hull parameters, the Diameter was set at D=2.55m, using this with Va we were able to consult
the Bp-δ charts for a B-series propeller and select values of Bp, then solve for n and δ to use for the ηo
optimization. Iterations were done through the 5 bladed propellers and cavitation was checked. Below
are the equations used and a table of the selection process for the chosen B-series propeller.

8 210.979 122.2446 0.96 0.7
Cavitation Check
To check cavitation, the height of the prop was set at 4.2m below the waterline. This resulted in a static
pressure of 143314.454 N/m2, Pv was assumed to be 3000 N/m2.
Next the reference velocity is obtained by (12.14):

ICE class 1-C Correction
As mentioned previously to correct for an ICE class 1-C propeller, the KT and KQ values were altered to
obtain a new open water efficiency. From the advice of Dan Mcgreer, to correct for the ICE class 1-C
propeller, the KT value was decreased by 3% and the KQ value was increased by 3%.
With D, and P/D set KQ, KT, and J were solved for as a function of n with the deduction taken into
account. Below are the equations used.
Using the charts to solve for the new operating point, a new efficiency was solved for. Below are the
open water efficiencies for the three operating speeds:

To account for the difference of ICE class:

Appropriate open water efficiencies were read from the tables, below is a summary of the results for
the three operating speeds:

Using the thrust deduction, the hull efficiency was solved for:

Taking this value, the required shaft power for the propulsion plant was solved for. Assuming a relative
rotative efficiency of 0.98:

Incorporating the integrated electric plant, a switchboard efficiency of 0.98, transmission efficiency of 1,
